Engine Repair in Rockwall, TX

How does an engine work?

Chevrolet, Honda, Mercedes-Benz, Ford, and other makes may have different types of engines inside them, but they all work the same way. Simply put, an internal-combustion engine (the engine found in vehicles) is a heat engine that converts energy from the heat of burning gasoline to mechanical work, or torque. The torque is applied to the wheels, which make your car move. Engines have pistons that move up and down metal tubes called cylinders. Pistons are connected to a crankshaft via rods, and move up and down to power the crankshaft, which then power the wheels of your car. Vehicles will have between 2 and 12 cylinders in its engine.

An engine’s pistons are powered by thousands of controlled explosions created by mixing fuel with oxygen, creating combustions. The heat and expanding gases from these mini-explosions push down on the piston in the cylinder, causing movement. Engines need air (namely oxygen) to burn fuel. During the intake stroke, valves open to allow the piston to act like a syringe as it moves downward, drawing in ambient air through the engine’s intake system. When the piston reaches the bottom of its stroke, the intake valves close, effectively sealing the cylinder for the compression stroke, which is in the opposite direction as the intake stroke. The upward movement of the piston compresses the intake charge. We at Horizon Auto Center in Rockwall know all about how engines work, and can make the appropriate repairs as efficiently as possible.

What are the different types of engines vehicle has? 

Depending on how much power the vehicle manufacturer wants the car to have and how much room is available beneath the bonnet, car manufacturers use different cylinder configurations for their engines. Here are some of the most common car engine cylinder layouts: 

  • Inline: An inline engine layout has its cylinders are arranged side by side in an upright position across the engine bay, particular to the car. This arrangement means the engine is small and compact, with the other components of the car (battery, cooling system, radiator) fitted around the outside. These engines are the most common; they can be found in hatchbacks and in small family cars.
  • Straight: Straight engines have its cylinders arranged in a line parallel to the car from front to back. This configuration means more cylinders can fit in the engine. Straight engines are typically found in powerful cars like BMWs and Mercedes.
  • V: A V engine’s cylinders are arranged, as the name suggests, in a V (when viewed from the front). The cylinders are mounted on their side at a 60 degree angle, with two rows facing outward. The rows are connected by a crankshaft at the base of the V shape. A V engine can fit a lot of cylinders, so they are commonly found on supercars and other premium vehicles. 
  • Flat: A flat engine’s cylinders are mounted horizontally, with two rows facing outwards. These engines are well known for having a low center of gravity within the engine bay. Porsche is one of the largest manufacturers of flat engines, which they use in their 911 sports car. 


How do I know if my engine needs repairs?

A vehicle’s engine is an intricate machine that is fundamental to getting you from one destination to another. Because of this, you should not ignore any issues with your engine. It is always a good idea to bring in your vehicle for smaller engine fixes rather than wait for a larger problem to occur that could cause severe damage to your car and cost you a lot more. If you are concerned about the health of your engine, you can bring your vehicle to  Horizon Auto Center in Rockwall. We specialize in engine repair and more! We can determine if the problem lies in your engine head gasket, exhaust system, catalytic converter, or something else.

Here are some of our tips for preventative maintenance to keep your engine running smoothly and avoid major problems: 

  • Change your oil regularly and use the recommended weight of oil.
  • Change your timing belt at your manufacturers’ recommended interval.
  • Give your engine time to warm up before driving if possible, especially when the weather is cold. This will let the oil get into all parts of the engine before putting a large load on the engine.

Some warning signs of a faulty engine include:

  • Your vehicle’s “Check Engine” light is on.

Your vehicle’s dashboard lights is your car’s way of alerting you when something is wrong. The “Check Engine” light is the most versatile of the dashboard lights. This light turning on could mean the oxygen sensor needs replacing, the catalytic converter is damaged, the fuel cap is loose, or something else. Whatever the reason is, a “Check Engine” light should not be ignored.

  • The engine does not start when you turn your key in the ignition.

This usually indicates a problem with the way your engine processes fuel. 

  • Your vehicle is consuming more fuel than usual (you are getting less miles per gallon).

If you are experiencing this issue, it means there is a problem with the way your engine is processing fuel. This coupled with a “Check Engine” light means you should bring your vehicle in to Horizon Auto Repair right away.

  • You feel shaking and/or hear strange noises coming from underneath your vehicle’s hood.

A knocking noise coming from beneath your vehicle’s bonnet is a surefire sign of a dying engine. It probably means your engine’s parts (pistons, bearings, etc.). If you experience this, you can give us a call at 469-430-0549 so we can get you in our shop as soon as possible.
