Isuzu Industrial Engine 4JG1T Diesel Engine 63 kW (85 PS) @2500rpm
Product Description
Isuzu Industrial Engine 4JG1T Diesel Engine
Isuzu J engin 4JB1T -The 4JG1T engine is a turbocharged version of the 4JG1.
Notable differences include a reduced compression ratio of 18.1:1
The J-series direct injection diesel engine was introduced in 1985, in 2.5 or 2.8 liter displacements. Initially installed only in lighter duty versions of the Isuzu Elf, it sound found its way into other Isuzu products. It replaced the somewhat smaller C engine; later on 3.1- and 3.0-liter versions were also introduced - still with four cylinders in line.
4JG1T The 4JG1 engine has a trochoid type oil pump, gear driven from the camshaft. The fuel system operates by plunger and nozzle and is of the high pressure solid injection type (Zexel in-line Bosch A-type). The starter motor is a 12 V unit. The firing order 1-3-4-2.
