Do Trucks Really Lose Horsepower With Age? How Does This Work? – II

Posted at Wed, Jul 27, 2016 11:45 AM

Compression isn’t the only thing wearing down your truck's power. Carbon deposits can also decrease the horsepower of your engine significantly. You can find them on valves, pistons, and spark plugs which aid in powering the car. If they are left untouched for a long time, they can cause problems with power.

Carbon deposits are formed on intake valves and valve seats when heat from the engine dries up the fuel sprayed onto them. The valves will then be unable to close properly, letting air out during compression. This causes the compression ratio to reduce and lead to a loss of power.

If carbon deposits are formed on cylinder walls and piston rings, you can see hot spots on them which cause knocking. To reduce this effect, the engine may subject itself to retarded timing, where the timing of fuel ignition is changed, and cause power reduction.

Carbon deposits are also a by-product of combustion in the combustion chamber. A spark plug riddled with carbon deposits can misfire easily. By cleaning spark plugs regularly, you can avoid losing power.

Deposits can also travel to various other parts of the car and cause major problems with the engine, making it unable to work properly. Power loss is one of many issues you face due to the formation of these carbon derivatives.
