Abstract
Although the brake thermal efficiency of the state-of-the-art Atkinson-cycle
hybrid engines have reached 41%, such engines typically have a low specific
power. The ideal hybrid engines for SUVs should have a high thermal efficiency
as well as a high specific power. Jiangling Motors recently developed a
4-cylinder, 1.5L TGDI hybrid Miller engine for powering mid-size SUVs, which has
achieved 42% brake thermal efficiency, 19.3-bar BMEP, and 73.3-kW/L specific
power. The engine has a high compression ratio, a long stroke, and is equipped
with a low-pressure EGR system. It can operate with the stoichiometric mixture
on the full engine map, with the help of the water-cooled exhaust manifold and
the intelligent thermal management system.
