There are several causes for high fuel consumption in a diesel engine. These include a difference in the weight of the vehicle, increased usage of air conditioning, and a difference in tire pressure.
Several problems can cause high fuel consumption. An engine that needs a tune up, a slipping transmission or a problem with a sensor giving bad information to the computer can all cause low fuel economy.
High fuel consumption on an EFI could be caused by a bad O2 sensor. Another reason for high fuel consumption is a dirty air filter or oil filter that needs to be changed. Electronic Fuel Injection vehicles are also famous for clogged fuel injectors.
Most common cause of unusually high fuel comsumption is a fuel leak. Other possiblities include leaking injectors, faulty O2 sensor, vacuum leak or incorrectly adujsted intake valve.
Poor driving habits, poor air intake, improperly adjusted fuel pump, excess operating RPMs.
High fuel consumption
Yes but not by much.
Of course there is,fact is when the four wheel gear is engaged,the vehicle aquires a high momentum force and as such,the front and rear diffs are in motion perpecuated by the propeller shaft.Despite the force applied on the vehicle in its locomotion,it necessitates high amount of fuel,as the motorist presses the accelerator cable impactly.Besides, when the 4 wheel gears are not engaged, then there is no room for differing fuel consumption .If at all it inherently comsume the fuel unexpectedly,then its better to visit a mechanic and ask him to adjust the consumption rate,by ncautionining him to rectify the injector pump screw,or service the pump it self.Of course there is,fact is when the four wheel gear is engaged,the vehicle aquires a high momentum force and as such,the front and rear diffs are in motion perpecuated by the propeller shaft.Despite the force applied on the vehicle in its locomotion,it necessitates high amount of fuel,as the motorist presses the accelerator cable impactly.Besides, when the 4 wheel gears are not engaged, then there is no room for differing fuel consumption .If at all it inherently comsume the fuel unexpectedly,then its better to visit a mechanic and ask him to adjust the consumption rate,by ncautionining him to rectify the injector pump screw,or service the pump it self.
Service it
Frequent fuel consumption can lead to high costs and environmental impact due to increased emissions. Streamlining reduces drag on the vehicle, improving fuel efficiency. If the force from the engine is moving at a constant speed, streamlining helps maintain that speed more efficiently.
Yes it sure can.
generally speaking, fuel consumption is higher in low gears because the rpm of the engine is higher. Performance is measured in kilometers/gallon. You have to consider that cars are designed for optimum performance when you drive at around 80 km/hr. For each car there is an optimum ratio distance/fuel consumption.
