- ENGINE RUN-ON, DIESELING -- RO-101. DIESELING, that nasty tendency of an engine to continue to run on, coughing and sputtering, after the ignition is turned off and there is no more spark. Run-on by dieseling is caused by fuel in engine igniting without spark. Possible explanations: a.) Running winter fuel in warm weather.

How a diesel engine works for a diesel engine is 20:1, compared with 9:1 for a petrol engine. Compressions as great as this heat up the air to a temperature high enough to ignite the fuel spontaneously, with no need of a spark and therefore of an ignition system.

Dieseling Dieseling or engine run-on is a condition that can occur in spark-plug-ignited, gasoline powered internal combustion engines, whereby the engine keeps running for a short period after being turned off, due to the engine kicking back upon shutdown, drawing fuel through the carburetor, into the engine and igniting it without a spark.

How does a Car Engine work? A motor car engine is an Internal Combustion Engine (ICE). Energy is created by burning either diesel or petrol in a combustion chamber. In such an engine, the energy is transferred from the pistons moving up and down at high speeds. This up-down motion is converted to a rotary motion through the crankshaft and axle.

How Fuel Injection Systems Work The engine control unit (ECU, the computer that controls all of the electronic components on your engine) sees the throttle valve open and increases the fuel rate in anticipation of more air entering the engine.

- Watch this animation and you'll see that a car engine makes its power by endlessly repeating a series of four steps (called strokes): 1  Intake: The piston (green) is pulled down inside the cylinder (gray) by the momentum of the crankshaft (grey wheel at the bottom). 2  Compression: The inlet valve closes.

- A steam engine uses external combustion, as opposed to internal combustion. Gasoline-powered cars are more efficient at about 25-28% efficiency. In theory, a combined cycle steam engine in which the burning material is first used to drive a gas turbine can produce 50% to 60% efficiency.

How a Crankshaft Works All the engine’s pistons are connected to the crankshaft by individual rods. The cylinders work in concert as well as with other engine parts. This is referred to as the four-stroke cycle and occurs in each of the four cylinders.

How Does A Radial Engine Work? A radial engine works like any other four-stroke internal combustion engine. Each cylinder has an intake, compression, power and exhaust stroke. They differ from inline and horizontally opposed engines in their firing order and they way they connect to the crankshaft.

Greg's Engine & Machine Connect the tester to a cylinder and turn the engine over about 6 to 8 compression strokes. You will be able to hear the cranking speed slow as the tested cylinder comes up on it's compression stroke. Note how fast the compression increases and jot down the highest reading.

How Do Steam Engines Work? The purpose of an engine is to provide power, a steam engine provides mechanical power by using the energy of steam. Steam engines were the first successful engines invented and were the driving force behind the industrial revolution.

Open/Closed Loop Operation When the engine is first started the system goes into open loop operation. 1  In open loop, the ECM calculates the Air/Fuel ratio based on inputs from the coolant and MAF sensors. The system remains in open-loop until the following three conditions are met: 2  Coolant temperature above 105°F.

How to prep and start a rebuilt engine Safety First! Make sure you have proper tools as well as eye protection. If the car is on the ground, be sure the wheels are chocked and the transmission is in neutral. Be sure to check the oil level in the engine and prime the oil system. Run the engine between 2,000 and 2,500 rpm, with no-load for first 30 minutes.

Why does my engine still try to run after I shut it off? This is common on engines that run way too rich or have oil burning problems. Dieseling is a common problem with high compression / high performance engines, especially in warm weather or when the engine is hot. In this case, it is usually caused by running cheap gas with inadequate octane. In this case it can usually be remedied by switching to a higher octane fuel. In milder street engines, another big cause for engine run-on is having the idle set too high, or the carb is misadjusted which requires the idle speed screw to be screwed-in too far to allow the engine to idle.

- 1 Power: As the air fuel mixture ignites and burns, it pushes the piston down, driving the crankshaft (red wheel at bottom) that sends power to the wheels. 2  Exhaust: The green outlet valve on the left opens to let out the exhaust gases, pushed out by the returning piston.

How Car Engines Work ­The purpose of a gasoline car engine is to convert gasoline into motion so that your car can move. Currently the easiest way to create motion from gasoline is to burn the gasoline inside an engine. Therefore, a car engine is an internal combustion engine -- combustion takes place internally. Two things to note:

How Car Engines Work Internal Combustion. The ­principle behind any reciprocating internal combustion engine: If you put a tiny amount of high-energy fuel (like gasoline) in a small, enclosed space and ignite it, an incredible amount of energy is released in the form of expanding gas. You can use that energy to propel a potato 500 feet.

Engine A V6 internal combustion engine from a Mercedes car. An engine or motor is a machine designed to convert one form of energy into mechanical energy. Heat engines, including internal combustion engines and external combustion engines, burn a fuel to create heat, which then creates a force. Electric motors convert electrical energy into mechanical motion; pneumatic motors use compressed air and others—such as clockwork motors in wind-up toys—use elastic energy.

What actually controls fuel injectors on a car, the COMPUTER (ECM) or Sensors on the Throttle body like? When you turn on the key, the computer gets the fuel pump to run for 2 seconds, opens up the injectors to get the gas, and sends current to the distributor to fire the sparkplugs. If after the 2 second spurt of gas, the engine doesn't start, the computer shuts down the pump, the injectors and you are not starting.

How Do Pistons Work? A: A piston is a cylindrical plunger that moves within a metal cylinder through the four strokes of the engine cycle: intake, compression, power and exhaust. While their motion is predicated on other engine parts and the mixture of air and fuel, the motion of a piston is central to the functioning of an engine.

How Police Cars Work High-performance engines - Police departments have to strike a balance between power and economy. While a few cars may be equipped with V8 engines for chases or highway work, the bulk of the patrol fleet will usually have V6 engines, which use less fuel. In either case, police cars require engines that can endure severe use. Upgraded alternator - The alternator takes energy from the running engine and coverts it into electricity to run lights, sirens and other electrical systems and equipment. Police cars use alternators that can crank out 225 amps or more.

How Car Engines Work 1 There is such a thing as an external combustion engine. 2  A steam engine in old-fashioned trains and steam boats is the best example of an external combustion engine. 3  The fuel (coal, wood, oil, whatever) in a steam engine burns outside the engine to create steam, and the steam creates motion inside the engine.
