INTRODUCTION Recently, because the price of fuel keeps going up and up, fuel consumption has become a big part of every sales discussion. You cannot win this discussion without knowing some facts. Most importantly, you must understand the facts and translate them into a favorable position for yourself and Case equipment. When customers ask about fuel consumption, they could be looking for four different answers. 1. How long can I work on a tank of fuel? The answer to this question depends more on the size of the fuel tank and how hard the machine is working than it does on the fuel efficiency of the machine. 2. How many gallons per hour does the machine consume? The answer to this question is “it depends.” It depends on the application, the operator, the quality of the fuel, altitude, options, attachments, tires, bucket capacity, etc. If the customer's number one priority is fuel consumption, then recommend purchasing the smallest machine possible, because it will consume the least amount of fuel. Of course, this is not what the customer wants to hear, as a smaller machine will not be capable of the productivity that is needed. 3. What is my productivity per gallon of fuel? The answer to this question is also “it depends.” Productivity is certainly a criteria that is more important than the first two questions, as productivity is the reason why a machine is purchased. 4. What is my productivity per hour? This question is not normally asked, but should be. Again, the answer is “it depends.” If the customer can understand productivity per hour in conjunction with productivity per gallon, that customer will have a good handle on operating costs. EPA auto stickers, which indicate rated city and highway miles per gallon figures, typically provide fair comparisons of fuel efficiency. They give the consumer an easy way to compare fuel efficiency when deciding to purchase a car. The Federal government requires the auto industry to publish these figures on all new cars. Construction equipment manufacturers publish little information on fuel consumption, primarily because it isn't very useful without an explanation. Operating conditions must be known to predict fuel efficiency for a specific use. While consumer vehicles travel on smooth roads with little grade (so rolling resistance is almost constant), construction vehicles work on sites where ground conditions vary considerably. The speed a unit is driven, the percentage of time in torque converter or hydraulic stall, and the loads lifted and carried have a great impact on the fuel efficiency of a construction vehicle.
3
So, is there a good, reliable and repeatable means to compare the relative fuel efficiency of similar construction machines? Engineers have developed a reliable and accurate method for comparing and predicting fuel consumption, called “Specific Fuel Consumption” (SFC). Power generated by an engine is measured in different ways (i.e., draw bar, flywheel, PTO, etc.). For our purposes, we will deal only with flywheel power, also referred to as brake power. This is referred to as BSFC, or Brake Specific Fuel Consumption. BSFC measures fuel consumption on a test stand at rated power, rpm, torque and other parameters. Detailed engine graphs list such performance measurements under very controlled and specific test conditions. BSFC, is expressed in pounds of fuel per horsepower hour. It eliminates the fuel density factor (cold “winter fuel” weighs less per gallon than warm “summer fuel” and provides less energy per gallon), but takes into account idling (running only parasitic devices) and duty cycle. Note: The problem with this measurement is that construction equipment does not work at constant power, torque load or rpm. Therefore, this measurement only serves as a relative indicator of fuel consumption, but does not come close to measuring actual fuel consumption. To understand actual fuel consumption, you must understand the duty cycle of the machine. The duty cycle is usually listed as light, medium or heavy, or as a percent of advertised, rated power. Duty cycle can be defined as how hard a component, device or system is operated. A generator set or irrigation pump are about the only applications where 100% of an engine's power setting can be used. However, BSFC only measures bare engine performance. It does not consider the efficiencies of the hydraulic, cooling, powertrain or other systems that greatly influence the fuel efficiency of a construction machine. Also, BSFC changes with engine rpm and load. Therefore, it must be graphed to be understood. It's a moving target. You must pick a specific RPM and load factor (horsepower) to read this number. For an example of how a hydraulic system can affect fuel consumption, consider the 580Super M and 590 Super M with a fixed displacement gear pump versus the 580 Super M + and the 590 Super M + with a variable displacement piston pump. The plus machines will burn less fuel doing the same work as the standard models. When estimating fuel consumption, the plus units will fall between a 30% to 60% load factor, whereas the standard configuration will fall between a 40% and 70% load factor. This saves about 10% on fuel cost for the same amount of work.
4
Can fuel efficiency of construction machines be accurately compared? Most people try to compare gallons per hour (gal/hr). A better measurement is yards per gallon (yds/gal), but yds/gal does not take production rate (yds/hr) into consideration. In addition, productivity (yds/hr) must be considered when evaluating equipment. This Product Information Bulletin discusses several factors that determine machine efficiency. It will give you the ability to understand fuel economy comparisons made by Case and its competitors.
FACTORS AFFECTING FUEL CONSUMPTION Several factors impact fuel consumption of construction equipment. These include the operator and the equipment design, including the size of the fuel tank, machine maintenance, the weather, the altitude of the work site and the blend of fuel, among other factors. The significance of these factors can be determined by answering a few questions.
Does the operator affect the fuel consumption of a unit? Fuel consumption can vary greatly depending on how hard a machine is driven. Tire slippage consumes energy. A more experienced, consistent operator consumes less fuel and moves more material per gallon than a novice. Operating techniques that conserve fuel can be learned. An operator who conserves fuel does the following: •
Stops the engine during non-productive times
•
Throttles down and shifts up for travel
•
Uses more cycles with fewer overloads for digging machines like excavators
•
Reduces torque converter stall for loaders and dozers
•
Avoids working in a gear that's too high. With torque converter machines energy is wasted in the form of heat (i.e., a gear that’s too high runs hydraulics over relief and generally overloads a machine with torque converters or variable displacement pumps).
•
Is aware that moderate, constant loading of the machine is fuel efficient
•
Sets up the site and plans the order of material movement to minimize the number of moves with the least amount of up-hill movement
•
Takes advantage of the terrain, such as dozing down hill
•
Avoids spinning tire and tracks, as this not only wastes fuel, but accelerates wear and tear
5
Does machine design affect fuel consumption? Do parasitic losses affect fuel consumption? “Yes” is the answer to both questions. Overall, machine efficiencies are the result of a balance of engine, power train and hydraulics as well as the control of these systems. Case equipment makes extensive use of electronic control systems such as idle management, hydraulic fan management, auto shift, multiple power modes, settings per operator preference, machine diagnostics, and more. In addition to electronic control systems, other Case features contribute to reducing fuel consumption and increasing productivity, such as limited slip axles, hydraulic fans, viscous fans, wastegate turbochargers, easy-fill buckets, pilot controls, hydraulic couplers and many others. Many Case products such as wheel loaders, excavators and some loader backhoes use pressure compensating hydraulic systems which consume less power, run cooler and provide greater productivity (more yards/gallon). The open center system is constantly flowing, even when it is not working, which consumes energy and generates heat. Transmission ratios, tires and tracks, blade size, shape of bucket and other design factors can improve or degrade fuel efficiency. An inefficient design consumes more fuel to move the same amount of material. Fuel-efficient machines employ systems that control engines, hydraulics and powertrains, and minimize lugging (overload). Lugging burns more fuel and accelerates wear.
Does fuel tank size affect fuel consumption? Yes, fuel returned to the tank from the injection system becomes warmer in a small tank. Warm fuel reduces engine efficiency, so it produces less power. The engine must work longer to move the same amount of material. Many manufacturers address this issue with larger fuel tanks. In addition, some Case products utilize a fuel cooler to extract more energy from the fuel.
6
Does proper maintenance help maximize fuel efficiency? Yes, proper maintenance helps to maximize fuel efficiency. Maintenance tasks that affect fuel efficiency include the following: •
Adjusting belts to the proper tension – Case equipment with Case engines use auto belt tensioners
•
Replace fuel, oil, and air filters at scheduled intervals or more often in severe conditions
•
Replacing worn bucket teeth and cutting edges (to reduce friction, which improves fuel efficiency)
•
Keeping tires properly inflated and replacing badly worn tires to maintain traction (i.e.,spinning wheels waste fuel)
•
Replacing worn piston seals on hydraulic cylinders (passing oil at high pressure generates heat and wastes energy)
•
Keeping tracks adjusted for ground conditions
Through proper maintenance, the gallons of fuel used per hour are reduced and more hours can be worked with the same amount of fuel. Case consistently leads the industry in the SAE Maintainability Index, which in turn helps Case products lead the industry in fuel efficiency.
Does weather affect fuel efficiency? Yes, for several reasons. When used in cold weather, fuel provides less energy per gallon, so more fuel must be used. In extremely cold weather, additives are used to minimize gelling of the fuel, again reducing the amount of energy it can provide. Working conditions are tough when digging through frost. Wet, muddy conditions also reduces productivity due to spinning wheels, mud sticking to the buckets, and other factors. This reduces the yards of productivity per gallon of fuel.
Do machines burn different quantities of fuel depending on altitude? Yes, there is less combustion air at higher altitude, so performance is diminished. Engines equipped with turbo chargers compress the air to deliver more to the combustion chamber, for better performance. Consequently, a turbocharged engine is much less affected by the thin air at higher altitudes than a naturally aspirated engine. Although turbocharged engines can use more fuel, they use it more efficiently, resulting in higher productivity. As a result, such an engine moves more material, resulting in more yards per hour and more yards per gallon.
7
Are there differences in fuel quality that translate into gallons burned per hour or per yard? Yes, fuel quality varies depending on how the fuel has been blended. Blending guidelines have been established, but there is no universal standard. Cetane (affects starting), density (the real indicator of how much heat energy is available), sulfur content, contaminates and additives, along with formulations for winter fuels, vary substantially among fuel providers. These variations can make a significant difference in fuel efficiency.
CASE FEATURES THAT CAN IMPROVE PRODUCTIVITY AND FUEL EFFICIENCY Manufacturers often use viscous, clutched or hydraulically driven fans to improve fuel efficiency or reduce fuel consumption. Case wheel loaders and motor graders feature hydraulically driven fans. Wheel Loaders have an optional Reversing Fan that is temperature controlled. This keeps the coolers clean and allows the fan to rotate only as fast as necessary. Case wheel loaders feature a multiple power mode which allows the operator to choose performance or economy or in-between. They also feature idle management to reduce fuel consumption for those applications or conditions that require long periods at idle. Case loader backhoes use a viscous fan which consumes less energy in cool temperatures, yet provides maximum cooling in hot temperatures. Case dozers feature operational preference features such as max speed settings, steering speed, shuttle speed and reverse ratio settings. The reverse ratio allows the operator to travel in reverse at a faster speed ratio than forward, so the engine can be throttled down while still maintaining a reasonable reverse speed.
8
WHAT’S THE PURPOSE OF ALL THIS? Numbers do not lie, but from a comparison standpoint they are certainly subject to many controllable and uncontrollable factors. The Burlington proving grounds recorded fuel consumption of 2.2 gph for a 580SM Series 2 loader backhoe performing a combination of loader and backhoe work at a medium load factor. Light duty could consume as little as 1.8gph and heavy duty as much as 3.3 gph. Fuel Consumption Comparisons The chart on the following pages lists fuel consumption of Case models at 50% and 30% load factors. If you need a load factor other than 50% or 30%, simply double the 50% load to get 100%, then multiply it by the load you need. For instance, a single drum roller working steady all day could be working at a 65% load factor. Roller work is typically a higher load factor than most products as the engine is driving two hydrostatic systems, one for vibration and one for the drive system. Both of these systems are frequently starting and stopping a lot of weight. For the SV210, the fuel consumption at 65% load factor would be 3.54 gallons per hour. See if you can come up with the same results. As mentioned previously in this bulletin, it is important to recognize that many factors affect the fuel efficiency of a machine. Machine design, operating conditions, operator skill level and other factors significantly impact fuel efficiency. Use this data cautiously to explain the factors listed in this bulletin.

SUMMARY When the subject of fuel economy comes up in a sales discussion, remember that productivity or yards per hour is the first reason a customer buys a machine. The second consideration should be how much work can be accomplished per gallon of fuel or yards per hour. The lowest priority when buying a wheel loader is how much fuel will be consumed per hour. If fuel consumption is the primary consideration when purchasing, the customer should buy a smaller wheel loader. For example, when comparing the Case 921E wheel loader to the Volvo L150E, the Volvo wins the fuel per hour comparison, the fuel consumed per yard is close to even, but with regard to the all-important measurement of yards per hour, the Case 921E is king of the hill. Understanding the variables affecting productivity and fuel consumption is important in controlling overall machine operating cost. By teaching these simple guidelines to your customers, you will help them maximize productivity and the long-term value of Case Construction Equipment.
