Features of fuel efficiency of tractors, trucks, and passenger cars
The paper presents the results of studies on the influence of fuel system malfunctions, engine adjustment violations, technical condition, and operating conditions of tractors, trucks, and passenger cars on fuel consumption. The analysis of external speed characteristics of diesel and carburetor engines is carried out. The influence of ignition timing, fuel equipment condition, tire pressure, cooling system operation, and maintenance quality on fuel efficiency indicators is considered. It is shown that untimely maintenance, improper adjustment of engine systems, and violation of operating requirements significantly affect fuel consumption and engine performance. The results of the study demonstrate that the technical condition of vehicles and operating modes are among the main factors determining fuel efficiency indicators.
