In a dual fuel engine a primary fuel that is generally gaseous
is mixed with air, compressed and ignited by a small
pilot spray of diesel as in a diesel engine. Dual fuel
engines suffer from the problems of poor brake thermal
efficiency and high HC emissions, particularly at low outputs.
In the present experimental work, the effects of
intake charge temperature, pilot fuel quantity, exhaust
gas recirculation and throttling of the intake on improving
the performance of a LPG-diesel dual fuel engine have
been studied. Results indicate that at low outputs an
increase in the intake temperature and pilot quantity is
advantageous. HC level generally reduces with increase
in pilot quantity and intake temperature. Exhaust gas
recirculation (EGR) coupled with intake heating raises
the brake thermal efficiency and lowers HC emissions.
With throttling and EGR there is a significant reduction in
the HC levels and an im

没时间哦~汗,..相信聪明的你可以自己翻译的~!
呵呵
