The vast majority of vehicles manufactured after 1987 are fuel-injected: the injectors and high-pressure fuel pump immediately cease supplying fuel to the cylinders when the ignition is switched off. If the injector is damaged or dirty, a small amount of fuel can enter the chamber and be ignited, causing a sputter or two after the engine is ...
The end product of the PEM fuel cell was able to support the auxiliary systems of the truck using a maximum of 5 kW of power. This input was able to sustain the cooling chamber, cabin air-conditioning , radio unit, etc. [ 2 ] The introduction of this fuel cell also contributed to a 9% reduction in diesel fuel consumption and 9.6% reduction in ...
The truck recall is one of four issued by Ford on the same day, as follows: Ford also recalled more than 20,000 compact SUVs because of battery failure concerns impacting certain 2020-2024 Ford ...
E.g. in a truck with a Caterpillar C15 engine, it is achieved by going all the way up to 1950RPM, then shifting to a gear that will put the engine at 1500RPM. In contrast, using progressive shifting, i.e. maintaining maximum torque , the overall acceleration is slower but there is increased fuel efficiency and lower wear of the engine due to ...
This is done to increase fuel efficiency while under varying loads. Variable compression engines allow the volume above the piston at top dead centre to be changed. Higher loads require lower ratios to increase power, while lower loads need higher ratios to increase efficiency, i.e. to lower fuel consumption.
The EPA calculated that new trucks would save operators a total of $3.5 billion in fuel and other costs from 2027 to 2032, paying for themselves in two to four years.
These can be battery or fuel powered but in either case, use less fuel, do no harm to the vehicle's engine, and reduce or eliminate emissions. [3] Other vehicles, including police, military, service trucks, news vans, fire trucks, ambulances, and hydraulic bucket trucks can be equipped with mobile power idle reduction systems, similar to a ...
A start-stop system off button on a Perodua Myvi. A vehicle start-stop system or stop-start system (also known as S&S, micro hybrid, or micro hybrid electric vehicle (μHEV)) [1] automatically shuts down and restarts the internal combustion engine to reduce the amount of time the engine spends idling, thereby reducing fuel consumption and emissions.
