Abstract

The paper is dedicated to comparative analysis of cycles of engines supplied with natural gas having diesel compression ratio and quality power control with the basic diesel engine cycle. Two types of gas engines were investigated: with internal mixture formation and glow plug air-gas mixture ignition; with external mixture formation and air-gas mixture ignition with the help of pilot diesel fuel injection. Calculation results by external speed characteristics demonstrated that the gas engines were at least as good as the base diesel engines as regards to power and fuel efficiency. At the same time they have lower mechanical and thermal loads and considerably lower СО2 emissions.

Keyword(s): Natural gas powered engine, diesel engine, analysis of calculated cycles, fuel efficiency, СО2 emissions.
