Diesel engines — general information (Scorpio 1)

The engine with intermediate fuel injection into the combustion chamber, four-stroke, four-cylinder, in-line, water-cooled, has a camshaft in the cylinder block, installed longitudinally in front of the car. The cylinder block is cast from cast iron. The crankshaft has five bearings, with fixation from axial movement by thrust half rings, which are installed on the central main bearing. The statically and dynamically balanced flywheel is attached to the crankshaft with six bolts.

The pistons are made of aluminum alloy, with a recess on the bottom. The connecting rods are I-section, forged and heat-treated. The lower head of the connecting rod is fitted with liners, and the upper head is pressed with a bronze bushing.

The camshaft rotates in three bearings. In the central part it has a helical gear for driving the oil pump.

The cylinder head is made of aluminum alloy, with pressed-in guide bushings and valve seats. Each valve is closed by two springs, which transmit force to the valve through a plate fixed to the valve stem with crackers. The valves are controlled from the camshaft through rods, pushers and levers.

The Carret AiRtsearch T03 turbocharger has been installed since 1988 and is driven by exhaust gas energy. The compressor is located on the same shaft as the turbine. By forcing air into the cylinders under pressure, it increases the cylinder filling factor, which increases engine power and torque. The fuel system of a turbocharged engine is the same as that of a conventional engine, with the exception of a smoke reduction device, which consists of a valve regulating the boost pressure and a regulator of fuel supply to the high-pressure fuel pump.
