A major point of debate in fleet management is using diesel vs. gas cars and trucks. Choosing to purchase gasoline engines instead of diesel ones for medium-duty trucks may be an unpopular decision, but it s the right one.
petroleum to diesel engines, characterized in that the method comprises the following stages: a) feeding only with gas-oil up to 70% of the maximum power of the engine; and b) mixed feed of gas-oil and liquefied petroleum gas when the power exceeds 70% of the maximum power of the ...
Also, a diesel engine is simpler than a gas engine since it runs without spark plugs and the associated electrical system needed for them. Now, cars and SUVs can run on diesel and have performance more akin to a gas engine, but with the added gas mileage and reliability of a diesel. I...
Accidentally putting diesel fuel in a gasoline-powered vehicle is a more common mistake than one might think, especially since many fuel pumps often house the gas nozzle right next to the diesel nozzle. If a driver is not paying attention, they can potentially grab one over the other and att...
Nano-graphene lubricating oil with appropriate concentration shows excellent performance in reducing friction and wear under different working conditions of diesel engines, and has been widely concerned. Lubricating oil has a significant impact on partic

With full throttle at its torque peak (the point where each combustion event creates the greatest force), the gas engine is essentially limited by how much air-fuel mixture it can “inhale”, which depends on a variety of factors such a valve size, porting, etc. The poi...
Diesel engines only use direct fuel injection compared to gas engines, which use both port injection and direct fuel injection. Voyagerix/Shutterstock One big difference between a diesel engine and a gas engine is in the injection process. Most car engines use a combination of port injection, ...
To demonstrate the scalability for practical conditions, a full-size Pt1/TiO2 NA monolith with a Pt loading of 0.53 g L−1 and dimensions of Ф 5 cm × 7.5 cm was evaluated under highly transient feed gas conditions, mimicking a heavy-duty diesel (HDD) federal test proced...
Increasing focus on fuel efficiency and greenhouse gas emissions has created pressures to increase the NOx conversion efficiency and the durability of diesel SCR systems. In some respects, the SCR catalyst coupled with the diesel engine plays a similar role to the three-way catalyst on the ...
