Compression

In a vehicle there are hundreds of moving parts that get you from the point A to point B. The modern automobile is an intricate piece of machinery and a wonder of the technological processes. One of the main processes that produces a vehicle's power is called compression. Compression is the pressure of the air/fuel mixture that has been compressed in the cylinder of the engine by the piston. As the piston travels upward this mixture is compacted down into a smaller volume so it can be ignited by a spark plug. In a four stroke engine compression occurs on the upward stroke or the upward push of the piston through the cylinder bore before the spark plug ignites the mixture.



Octane Rating
Why should you read the octane rating at the gas pump? The compression ratio of your engine determines the octane required for optimum performance. The octane rating of gasoline states the level fuel that can be compressed before it ignites. Under extreme conditions such as heavy acceleration fuel can ignite without the use of the spark plug resulting in a "ping" or "pinging" and under ultra heavy condition a knocking sound. When this condition is left un-treaded it could result in sever engine damage.

The compression ratio is the number that can be used to help predict the engine performance. It is calculated by taking the volume of the cylinder, when the piston is at the bottom of its stroke, and then dividing it by the volume when the piston is at the top of the stroke, the higher the compression ratio the more power your engine can produce, The extra power produced is coupled with added efficiency in turn help improve gas mileage.

Checking Compression
To check compression you must first disable the ignition system to keep the engine from starting. Locate the ignition coil and disconnect it, or unplug the ignition module connector. To test if the ignition is disabled crank the engine over, the engine should not start. With the engine warm remove one of the spark plugs and insert the compression tester into the spark plug hole. Now turn the key of the engine for at least 5 to10 seconds to get an accurate reading. Repeat this for each cylinder of the engine and record your results relating the reading to the individual cylinder. If the individual readings vary by more than 10% between cylinders you may have a problem.

Optional compression testing methods include an electric starter tester. This test measures the battery amperage draw to each cylinder while the engine is cranking. It will show you which cylinders have good compression and which have the least compression. In a gasoline engine a moderate compression ratio is needed, around 140 to 160 pounds per square inch. Each manufacturer produces specific compression ratios for their engines to closely control the power output and emissions. If high compression exists it can cause a problem known as pre ignition or detonation. A compression test can detect internal combustion malfunctions such as, bad valves, bad piston rings, or excessive carbon build up. These problems if left un-repaired can cause more extensive engine damage and even catastrophic failure.

Black Smoke

Black smoke is caused by too much fuel being processed inside your car's engine and then released from the tailpipe of your car. Malfunctions in fuel delivery or internal system leaks will cause black smoke to come from the tailpipe. Before fuel injection became available in automobiles in the mid 1980's, the carburetor was the main fuel and air mixer in most vehicles. A carburetor was a simple device that supplied the engine with proper fuel to air mixtures. Carburetors performed two operations 1. meter air flow 2. deliver the correct amount of fuel to air mixture. This mix could be kept even during the wide range of extra factors associated with an engine such as high temperature, cold starting, hot starting, idling and acceleration.

Fuel Injector Cut Away

The primary difference between a carburetor and a fuel injection system is that the fuel injection system atomizes fuel by pushing it through a small nozzle under pressure, while a carburetor utilizes vacuum created by air flow into the intake manifold. Airflow in an injection engine is controlled by the throttle body; fuel is distributed directly in each cylinder. This creates better fuel control, lower emissions and faster acceleration. The process of measuring the amount of fuel a fuel injector is dispersing is determined by the ECM (engine control module). The fuel injection system has several parts: the mass airflow sensor or map sensor, throttle body, throttle position sensor, idle control valve, fuel pump, fuel pressure regulator, fuel lines
, and oxygen sensors.

Cause of Black Smoke
Black smoke is caused when the mix of fuel and air becomes un-balanced. Normal mixture is 14.5 parts air to1 part fuel. When the fuel to air mixtures change because of a malfunction the mixture can go as high as 14.5 to 2 or 3, two to three times the proper amount. The black smoke is the excess fuel generated from the rich mixture and can be cause by one of the following:

* Plugged Air Filter
* Shorted or stuck fuel injector
* Failed fuel pressure regulator
* Vacuum leak
* Shorted ECM Sensor

Trouble Shoot Black Smoke
Check Engine Light
If the check engine light is illuminated the ECM has detected a malfunction that could be causing the problem, scan the ECM to retrieve trouble codes and repair as needed.

Preventive Maintenance
To check your car's mixture you will need to use a gas analyzer to test your exhaust gases. This will measure the carbon monoxide, hydrocarbon, nitrogen oxide and oxygen content of your exhaust. During a normal smog inspection the fuel/air mixture is tested and a report generated. When a tune up is performed the spark plug end insulator can tell you whether you have a lean or rich mixture. Brownish grey is the desired color and confirms proper mixture. Black and sooty means the mixture is too rich while white to light grey confirms a lean mixture.

Fuel injection systems rely on pressurized fuel to operate. Maintaining this pressure is mandatory for the system to function properly. Replace your fuel filter with every tune up to keep your injection system operating properly.
