Why trucks and buses use diesel engine?

Because heavy vehicles such as buses operate continuously and in severe conditions, Diesel engines are more reliable because they don’t require an ignition system. The fuel ignites under compression. Diesel engines produce much more torque, which is needed to move heavy vehicles efficiently.

What kind of fuel is diesel?

Abstract: Diesel fuel is a mixture of hydrocarbons obtained by distillation of crude oil. The important properties which are used to characterize diesel fuel include cetane number (or cetane index), fuel volatility, density, viscosity, cold behavior, and sulfur content.

Who makes fuel cell buses?

Today, there are more than 1,300+ fuel cell electric buses powered by Ballard deployed globally.

Which type of trains use diesel fuel?

Diesel–electric locomotives (two examples are shown in Fig. 9.36) are in widespread use around the world. They have also been impacted by the availability of IGBTs with high power ratings. In these trains, diesel fuel is used to generate electricity.
