Advantages and Disadvantages of Diesel Engine

Advantages and Disadvantages of Diesel Engine Points : Advantages and Disadvantages of Diesel Engine Advantages

1. When evaluate to carburetor and electrical ignition system, injection equipment is more consistent and secure.
2. Fuel contain high self-ignition temperature is explosive. Suitable to its higher flash point and the hazard of fire is considerably cheap.
3. Diesel Engine is extra reasonable having thermal efficiency on 50% more than that of spark ignition engines and too contain high compression ratio, growth ratio and thermal efficiency.
4. Compression ignition engines canister be put to load at once after starting, though warm up period is essential to make sure adequate flow of the lubricating oil.
5. Its cheap r.p.m. and forceful assembly use high grade steel with bearing material longer period among overhauls are likely resulting in smaller wear and tear than the petrol engine because well as support in reducing maintenance cost.
6. It has no choke to contain the air supply at all speeds so; the volumetric efficiency is greater as the speed is lower at full load. These consequences in a extra uniform torque above a wide range of engine speeds as long as a improved top gear performance.

Disadvantages

1. Due to the high cost of exactitude of fuel injection gear in comparison to petrol engines, capital cost is higher resulting in considerably exclusive major overhauls which are less.
2. Engines are to get the structure of decompressed for rising the speed for heat making and resulting constancy as high compression ratio provide a small valve chamber space require the valve to be situated in the cylinder head.
3. Governor is built-in for compression ignition engine for grave engine speeds instead of vehicles speed as ready in the reduction gear transmission. It is a essential for idling and most b.h.p. happening under maximum r.p.m.
4. At stationary situation, they contain propensity to slow operation as well as vibration s and noise.
5. To make easy starting in lower density range as well as for the cranking speed which is incompetent for raising the temperature of the air to that essential for the self-ignition temperature of the fuel compression is needed.
6. Suitable to high pressure necessary to cylinder for combustion function, power to weight ratio is very low.
