Abstract

The performance of CY4102BZLQ turbocharged diesel engine with the HP60 turbocharger at different high altitudes was studied on the engine test bed for simulating high altitude(low air pressure). The conclusion indicated that the engine performance such as power and economy decreases with the increase of altitude, and the temperature of exhaust increases simultaneously. In addition, the rotational speed of the turbocharger and turbocharger ratio increase with the increase of altitude.
