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…
Four-Stroke Spark Ignition Engine
In this gasoline is mixed with air, broken up into a mist and partially vaporized in a carburettor . The mixture is then sucked into the cylinder. There it is…
Two-Stroke Cycle Diesel Engine
The cycle of the four-stroke of the piston (the suction, compression, power and exhaust strokes) is completed only in two strokes in the case of a two-stroke engine. The air…
Principles of Operation Of IC Engines: Four-Stroke Cycle Diesel Engine
In four-stroke cycle engines there are four strokes completing two revolutions of the crankshaft. These are respectively, the suction, compression, power and exhaust strokes. In Fig. 3, the piston is…
Constructional Features of IC Engine
The cross section of IC engine is shown in Fig. 1. A brief description of these parts is given below. Cylinder: The cylinder of an IC engine constitutes the basic…
Engine & Working Principles
A heat engine is a machine, which converts heat energy into mechanical energy. The combustion of fuel such as coal, petrol, diesel generates heat. This heat is supplied to a…
What is Keyless Entry and How Does it Work?
Keyless entry systems allow you to unlock and lock the doors to your vehicle without using a key. Most modern US vehicles are equipped with a basic keyless entry system…
Microcontroller vs Microprocessor
Selecting the right device on which to base your new design can be daunting. The need to make the right balance of price, performance and power consumption has many implications. First,…
Crankshaft position sensor
The crankshaft position sensor measures the rotation speed (RPMs) and the precise position of the engine crankshaft. Without a crankshaft position sensor the engine wouldn't start.In some cars, the sensor…
Accelerometers
Before you can understand accelerometers, you really need to understand acceleration—so let's have a quick recap. If you have a car that accelerates from a standstill to a speed (or, strictly…
