These diesel engines are extremely simple and are of closed crankcase design with all the working parts totally enclosed. These engines operate on 4 stroke principle at the relatively low speed of 1000 r.p.m. They are easy to maintain, economical to run and need minimum replacement of spare parts. Oil engines are widely used for pumps for irrigation purposes, Tube-Wells, Concrete Mixtures, Flour Mills and Rice Hurlers, Saw Mills, Rotary Oil Mills, electric generators etc. The combustion chamber with its comp. Ratio provides for easy hand starting even in winter for which 4 stroke diesel engine have on extremely good reputation.Combustion chamber is open type .This has cast iron piston in LR-4 type and aluminum alloy piston in LR-7 type engine, Respectively having four compression and one oil ring in LR-4 type and three compression and two oil rings in LR-7 type engine.
