Isuzu's New 3.27L Small Direct Injection Diesel

The 4BC2 diesel is a small DI engine of 3.27 litres displacement and maximum power output of 100 PS(73.6 KW)/3500 RPM(JIS) developed for small truck application. This paper describes comparative study results indicating that this DI diesel offers approximately 15% fuel economy advantage over IDI of the corresponding displacement and DI noise levels are 3-5 dB(A) lower at idling and the same or lower at full load compared with IDI. Also covered are the DI features which leads to improvement of coolant heat-up performance to the same levels as with IDI.
