What are the reasons for the high fuel consumption of Dongfeng Tianlong?
1 Answers
Incomplete combustion of diesel. Insufficient compression ratio, commonly known as air leakage. The main causes of air leakage are wear of cylinder liners, pistons, piston rings, poor sealing, valve leakage, and wear of valves or valve seats. Poor atomization of diesel. Aging of fuel injectors, plungers, or delivery valves, or improper adjustment of fuel injectors. Incorrect fuel injection timing. Clogged air filter, obstructed air intake. Incorrect clearance of intake and exhaust valves. Failure of the engine lubrication system, poor lubrication. Additional information: The fuel consumption per 100 kilometers indicated in the manuals of domestic vehicles is generally the constant-speed fuel consumption. However, since vehicles often experience various working conditions such as acceleration, deceleration, braking, and engine idling during actual driving, the constant-speed fuel consumption is often lower and significantly different from the actual fuel consumption.
