Shanghai diesel engine Q & A

Q1:What is the working principle of diesel engine?

A1:Diesel engines operate by drawing air from the environment(ambient air) into the cylinder during the intake stroke. Then, the air gets compressed highly with the piston movement(Cylinder up). Due to the high pressure and temperature in the cylinder, the diesel fuel gets injected and, consequently, ignites. The high-pressure gas forces back the piston(Cylinder down), which leads to the power stroke. Finally, the waste gas gets expelled from the cylinder through the exhaust valve to begin the next cycle.

Q2:What is the lifespan of a diesel engine?

A2:With proper maintenance, diesel engines can easily hit over 500,000 miles. Some even reach 1,000,000 miles, or in simple terms, ten years without a single problem.

Q3:What are the advantages of diesel engines?

A3:Diesel engines have numerous benefits. They are more fuel-efficient than gasoline engines because they use compression ignition and have higher energy content per unit of volume. Diesel Shanghai engines also offer better torque output. Additionally, diesel engines are durable and reliable. Finally, they have low maintenance costs.

Q4:What are the types of diesel engines?

A4:There are two major types of diesel engines. The first one is the four-stroke diesel engine, which entails four steps–two piston movements–of compression, expansion, and exhaust. The four-stroke diesel engine focuses more on fuel efficiency. It’s mostly used in vehicles that traverse on highways. The second one is the two-stroke diesel engine, which focuses more on the torque output. It’s mostly used in industrial applications such as the Shanghai marine diesel engine. Other types include direct injection diesel engines, which directly spray fuel into the cylinder, and common rail diesel engines, which use a high-pressured common rail to supply fuel to each cylinder via electronic injectors.
