Auto Engine Repair For Smooth Driving

It’s time for an engine repair if your car is having trouble making it up a short incline or losing power when accelerating to pass a long vehicle. Your Service Engine or Check Engine light may, or may not, come on warning you that a potential engine rebuild is needed. Instead of just a simple tune up service, your vehicle may require a more extensive engine repair.
Don’t procrastinate too long after you notice problems to call your auto shop and schedule a diagnostic test to determine the cause of the problem. It’s just like going to a medical doctor for an illness and following their prescribed course of treatment, you should follow your auto mechanic’s recommendations for engine repair. For safe and smooth driving ahead, keep your engine running at peak performance.
The inspection and diagnosis will also serve to let you know if your vehicle has any other components or systems that need maintenance and repair. Some of the engine components that could fail and cause problems are the . . .

• Crankcase – vent filter or ventilation (PVC) valve
• Distributor cap and rotor
• Emissions control system
• Engine sensors and diagnostics
• Fuel pump
• Ignition coil pack, module or wires
• Oil – top off or have an oil and filter change
• Vapor canister filter

To ensure that your vehicle will get you to your destination safely and smoothly, make sure you understand the type of engine repair that is recommended, and then have it taken care of as soon as possible. Don’t get stranded on the side of the road with a car that won’t run!

How Does Auto Engine Work?

An engine converts heat energy, created from burning air and gasoline, into mechanical energy (used to move your car). The car has a piston which moves up and down in the engine, and valves which open and close. It is a well choreographed machine which produces a lot of power. A piston goes up and down four times in order to produce one stroke of power.I could start the explanation anywhere along the path of the piston. I decided to start with the intake stroke.

Intake Stroke : This stroke starts with the piston at the top of its stroke.The intake valve opens as the piston starts to move from the top of its stroke to the bottom of its stroke. As the piston moves downward, it pulls in air and fuel. At the bottom of the stroke the intake valve closes.

Compression Stroke : With both valves closed, the piston moves up the cylinder compressing the air and fuel. Most cars have an 8 to 1 compression ratio. That means at the top of the stroke the air-fuel mixture is one-eight its original size.On a side note, as the piston compresses the air and fuel the temperature of the mixture increases.

Power Stroke : At the top of the compression stroke, with both valves closed, an electrical spark jumps the spark plug gap igniting the air and fuel. As the mixture burns, pressure builds up inside the cylinder.This pressure, which pushes the piston downward, creates the power to move your car. This is where heat energy is converted into mechanical energy.

Exhaust Stroke : When the piston is at the bottom of the cylinder the exhaust valve opens.As the piston moves up the cylinder it pushed the hot exhaust gases out of the engine.When the piston is at the top of its stroke, the exhaust valve closes and the intake valve opens.

This is called a “4 Stroke” engine because it takes 4 strokes to produce one power stroke.
