An engine is some machine that converts energy from a fuel to some mechanical energy, creating motion in the process. Engines - such as the ones used to run vehicles - can run on a variety of different fuels, most notably gasoline and diesel in the case of cars The different parts that make up your car's engine consist of: the engine block (cylinder block), the combustion chamber, the cylinder head, pistons, the crankshaft, the camshaft, the timing chain, the valve train, valves, rocker arms, pushrods/lifters, fuel injectors, and spark plugs.
The purpose of a gasoline car engine is to convert gasoline into motion so that your car can move. The engine is the vehicle's main source of power. The engine uses fuel and burns it to produce mechanical power. The heat produced by the combustion is used to create pressure which is then used to drive a mechanical device.
An inside look at the basic systems that make up a standard car engine.
Remove the old starter and place it with new one.
Remove the old alternator replace it with new one
Remove old water pump and replace it with new

An Oil Pressure sensor is often installed on the bottom of the oil pan. The engine oil pressure sensor is often quite similar to the oil level sensor, except that it measures the oil pressure after the oil pump. You will often find this sensor located at the engine block. The engine oil pressure sensor often has some plastic parts that can crack with age, which can cause it to start leaking before it malfunctions. You will mostly notice a bad oil pressure sensor by seeing a red oil pressure light on your dashboard.
Another critical sensor in your engine is the coolant temperature sensor. This sensor monitors your coolant temperature, which is a great way to determine your engine’s overall temperature. If it gets too hot, engine damage can occur. In some newer car models, the coolant temperature should shut off your engine once it reaches a high enough temperature.
Are your customers raving about you on social media? Share their great stories to help turn potential customers into loyal ones. Your vehicle’s engine needs to know how much air is coming in so it can optimize the fuel ratio for maximum performance. Your mass airflow sensor (MAF) measures the amount of air coming through the intake, so it knows how much it’s bringing in.
the air temperature coming into the engine is a critical part of maximizing engine performance. That’s why the intake air temperature sensor (IAT) tells the ECM the air temperature, so it makes adjustments and maximizes performance. The IAT sensor can either be separate or integrated into the MAF Sensor. Integrated into the MAF sensor is far more common on newer car models.
Oxygen sensors, also known as O2 sensors, measure your air-fuel mixture from the exhaust and the catalytic converter’s effectiveness (CAT). One oxygen sensor measures the air’s makeup before the CAT, and one measures the makeup of the air after the CAT. If there’s not enough of a drop in emissions, it lets the ECM know that you need to make repairs by showing a check engine light on your dashboard.
Knock sensors are there to make sure that your engine will not suffer from detonation or so-called knocking. Detonation or knock in a car engine is fatal for the internal parts This could also be from misfires or broken components, but if your engine’s knock sensor hears something – you have a problem.
Engine timing relies on a perfect symphony between the crankshaft and camshaft – and their respective position sensors let the ECM know precisely where each one is at. If those positions don’t line up to what they should be, you need to know as soon as possible. You do often have one sensor on the camshaft and one on the crankshaft. Some car models do only have a crankshaft position sensor
The throttle position sensor tells the ECM exactly how open the throttle is. That way, if there’s a problem between the pedal and the throttle, it won’t dump a ton of fuel in and damage the engine because of a sticky throttle. connection between the accelerator pedal and the throttle body is fully connected by electronics instead of a cable. Therefore, on the throttle body, there is a throttle position sensor to measure the throttle flap’s angle.
Your manifold absolute pressure sensor (MAP) sensor does exactly what it sounds like it would do – it measures pressure in the manifold. This takes your mass airflow sensor one step further by measuring how much air is actually making it to your engine. This is a critical component in fuel-injected engines as it optimizes your fuel ratios for the best possible performance. It also takes the job from the boost pressure sensor and measures the turbo pressure, if your car is equipped with one.
The fuel pressure sensor measures the fuel pressure on your fuel pressure line or at the fuel pressure rail. It is most likely to be mounted on your fuel pressure rail, but sometimes it can also be mounted on the fuel pressure line. It is critical for the engine control module to measure the fuel pressure, as an increase in pressure would result in a richer fuel mixture, and a lower pressure would result in a leaner fuel mixture.
If your vehicle doesn’t have enough coolant, it’s going to overheat. That’s why most vehicles come with a coolant level sensor, that way, you can avoid problems before you hit the road. If your vehicle doesn’t have enough coolant, then the coolant level sensor will light up the check engine light – and sometimes it will keep you from starting your vehicle.
The boost pressure sensor measures the boost pressure in the intake boost pipes. You do only have this sensor if your car is equipped with a turbo or supercharger.
