بررسی ترازنامه حرارتی در موتورهای اشتعال جرقه ای با سوخت گاز طبیعی در حالت پرخورانی

نویسندگان

چکیده

In this paper, the heat balance of an engine was investigated experimentally. The experimental work
was conducted on the EF7 natural gas fueled and turbocharged engine. The main goal was to develop
an empirical equation to be able to predict the heat balance of the engine at various loads and conditions.
The data were collected at four different conditions, two different loads and two different inlet coolant
temperatures, to include the effects of these parameters into the empirical equation. The exhaust energy,
power, coolant energy, and the other energies were determined either directly from the collected data or
indirectly calculated from the data. Based on the experimental results along with the engine specifications,
a mathematical equation was suggested. Different types of energy can be calculated from this equation
which shows a very good agreement with the experimental data.
