The Yaroslavl Motor Plant "Avtodizel" presented a new diesel engine of the YaMZ-336 family, designed for use in tractors, construction machinery, and other heavy equipment. The new engine features an in-line four-cylinder layout, liquid cooling, and turbocharging with intercooling.
The engine's power reaches 136 hp, and the maximum torque is 530 N·m. The design uses a Common Rail injection system with pressure up to 1600 bar, which should ensure more precise fuel delivery and stable operation under load.
One of the features of the YaMZ-336 is a monoblock cast iron cylinder head with eight valves. The cylinder block itself is also made of cast iron and has a monoblock design with dry thin-walled liners. The crankshaft is offset by 10 mm relative to the cylinder axis, and to reduce vibrations, engineers used a second-order inertia force balancing mechanism.
The engine received a classic overhead valve gas distribution scheme with a lower camshaft. Valve actuation is performed through tappets, pushrods, and rocker arms. The pistons are made of aluminum alloy.
Separately, the developers provided a load-bearing cast iron oil pan, which allows the engine to be used as part of frameless tractors. The design also allows for the installation of an air conditioning compressor and hydraulic pumps through one or two power take-off points.
