How to Solve High Fuel Consumption in Electronic Fuel Injection Diesel Vehicles?
1 Answers
When encountering high fuel consumption in electronic fuel injection diesel vehicles, there are two main solutions: 1. Adjust or replace the fuel injectors. The fuel supply system's performance, particularly the quality of the fuel injection pump and injectors, directly affects the combustion state of the diesel engine. Incorrect fuel injection pump flow rates or poor injector atomization are primary causes of inefficient combustion. Insufficient fuel injection pump pressure, poor injector maintenance, or delayed maintenance can lead to inadequate diesel atomization, incomplete combustion, and significant fuel wastage through leakage. This leaked fuel not only causes waste but also generates substantial carbon deposits in the combustion chamber, impairing the efficiency of both the diesel engine and turbocharger, further reducing engine output and increasing fuel consumption. 2. Adjust the fuel intake of the high-pressure fuel pump. The turbocharging system in diesel engines is an effective way to enhance power output and improve fuel economy. The turbocharger's operational condition significantly impacts diesel engine performance. Maintaining the turbocharger's boost pressure at a scientifically appropriate level is essential for ensuring the diesel engine operates in optimal condition.
