EXPERIMENTAL RESEARCH OF THE INFLUENCE CHARACTERISTICS OF THE ENGINE LCV ON ITS TRACTION-SPEED AND FUEL ECONOMIC PROPERTIES
The popularity of light commercial vehicles in the world is caused by its importance in the logistic system of the transport companies. Requirements of reliability, efficiency, performance in changeable conditions are submitted to these vehicles. Prototype with another engine was created on the basis of the production GAZelle «Next» car. The engines have similar values of power and torque. Powertrain wasn't changed. Thus, the volume changes making in the structure of the car was insignificant. The authors held the experiment to comparison of fuel economy and traction-speed characteristics for both engine variants. For this, measurements of the parameters operation of the engine and fuel consumption were carried out on the country distance routes. The analysis of the obtained data showed the difference in the field of engine load and fuel consumption. As a result, conclusion was made about the desirability of using one of the engines in specified conditions.
