Pilot Bearing
The pilot bearing or bushing is pressed into the end of the crankshaft to support the end of the transmission input shaft (Figure 10-7). The pilot bearing is a solid…
Flywheel
The flywheel is the mounting surface for the clutch (Figure 10-7). The pressure plate bolts to the flywheel face. The clutch disc is clamped and held against the flywheel by…
Diaphragm Pressure Plate
The diaphragm pressure plate (Figure 10-6) uses a single diaphragm spring instead of coil springs. The diaphragm spring is a large, round disc of spring steel. The spring is bent…
Coil Spring Pressure Plate
The coil spring pressure plate uses small coil springs similar to valve springs (Figure 10- 5). The face of the pressure plate is a large, flat ring that contacts the…
Clutch Construction
The clutch is the first drive train component powered by the engine crankshaft. The clutch lets the driver control power flow between the engine and the transmission or transaxle. Before…
Automotive Clutches
An automotive clutch is used to connect and disconnect the engine and manual transmission or transaxle. The clutch is located between the back of the engine and the front of…
Internal Combustion Engines
Internal combustion engines are devices that generate work using the products of combustion as the working fluid rather than as a heat transfer medium. To produce work, the combustion is…
Advantages and Disadvantages Of Two-Stroke Cycle Over Four-Stroke Cycle Engines
Advantages: 1) The two-stroke cycle engine gives one working stroke for each revolution of the crankshaft. Hence theoretically the power developed for the same engine speed and cylinder volume is…
Comparison Of CI And SI Engines
The CI engine has the following advantages over the SI engine. 1. Reliability of the CI engine is much higher than that of the SI engine. This is because in…
Two-Stroke Cycle Petrol Engine
The two-cycle carburettor type engine makes use of an airtight crankcase for partially compressing the air-fuel mixture. As the piston travels down, the mixture previously drawn into the crankcase is…
