Diesel Engine Cylinder Head and Valves

A diesel engine's cylinder heads perform several functions. First, they provide the top seal for the cylinder bore or sleeve. Second, they provide the structure holding exhaust valves (and intake valves where applicable), the fuel injector, and necessary linkages. A diesel engine's heads are manufactured in one of two ways. In one method, each cylinder has its own head casting, which is bolted to the block. This method is used primarily on the larger diesel engines. In the second method, which is used on smaller engines, the engine's head is cast as one piece (multi-cylinder head).

Diesel engines have two methods of admitting and exhausting gasses from the cylinder. They can use either ports or valves or a combination of both. Ports are slots in the cylinder walls located in the lower 1/3 of the bore. See Major Components of a Diesel Engine for examples of intake ports, and note their relative location with respect to the rest of the engine. When the piston travels below the level of the ports, the ports are "opened" and fresh air or exhaust gasses are able to enter or leave, depending on the type of port.

The ports are then "closed" when the piston travels back above the level of the ports. Valves (refer to figure 8) are mechanically opened and closed to admit or exhaust the gasses as needed. The valves are located in the head casting of the engine. The point at which the valve seals against the head is called the valve seat. Most medium-sized diesels have either intake ports or exhaust valves or both intake and exhaust valves

Safety Driving

Acquaint yourself using the dashboard of the vehicle. Your dashboard should display five different types of warning, such as the check engine light, oil pressure warning, an alternator warning, a temperature warning along with a brake warning. Learn how to recognize these different lights so that you can easily identify what needs your attention.

Save fuel by driving just like you possess a glass water located on your dashboard. This practice can help you avoid jack rabbit begins and quick stops. Every time you accelerate rapidly, the engine of the vehicle uses more fuel of computer would should you accelerate in a gradual rise in speed.

Look into the transmission fluid every 2 to 3 several weeks. Enable your engine run and open the hood of the vehicle. Make use of the transmission dipstick to determine the fluid levels. If there's insufficient fluid inside your transmission you most likely possess a leak somewhere in your body. It is advisable to go ahead and take vehicle to some auto technician so he is able to locate the leak.

Make certain the oil inside your vehicle is transformed about every 3,000 miles. Waiting longer to have an oil change can lead to grime and debris fouling your oil which can harm your engine. If you are using synthetic oil inside your vehicle, you simply need to alter the filter almost every other oil change.

Look into the radiator regularly. You need to enable your vehicle run for any couple of minutes, shut the engine and open your hood. Don't open the radiator when the vehicle is running. Check just how much fluid is incorporated in the radiator having a dipstick and bear in mind that you ought to always mix coolant with water before flowing it inside your radiator.

You should maintain the amount of your brake fluid. The brake fluid compartment is generally near to the engine and really should be looked into regularly. Make certain the compartment is 2 third full and increase the brake fluid if you want to. There can be a leak in your body should you frequently have to increase the brake fluid.

What makes a Colt

The Colt Cleartec is actually the newest design in a series of Mitsubishi cars that have been both chic and low cost for everybody since 1962.
Massive tombstone fuel-guzzling motors are fine and dandy when you're the king of some unknown wealthy country and can afford to tarmac an area the size of Luton for your own turning circle. But for decades the standard household living in a thriving city has been saving money whilst getting the highest quality possible by driving the latest style of Colt.
As Mitsubishi’s very first post-war passenger automobile, the Colt 600 made history when it was first manufactured in Okazaki, Japan in 1962. It was not long however until the renowned compact car touched down on European soil, with the Colt 1200 and Colt 1400 amazing drivers in the early 1980s. Before long everybody was queuing to be the first to take a Colt test drive.
By the mid eighties the world had joined the cult of the Colt, with both 3-door and 5-door designs developed, with a top engine capacity of 1800cc. The designs sold well in Europe, but they were extremely popular in Denmark, where they were among the country’s best selling cars.
Several versions of Colt have gone by diverse names around the world, such as the Dodge, Plymouth and the perfectly crazy Mirage Panther and Mirage Cyborg. Neither the Panther or Cyborg were built to be driven by any types of wild tiger or futuristic automaton, though debatably a futuristic robot might possibly drive one, though we can never know, because that would only take place in the future.
In the nineties cars ceased having all those well-defined angles and the corners became rounder in practically a real life precursor to web 2.0. The Colt remained in vogue and the fifth generation showcased a front wheel drive 1500 cc 8 valve SOHC caburettor engine in the base GL model, or a 1800 cc SOHC 8 valve EFI engine in the higher GLXi variant.
Currently the Colt Cleartec contains the most modern features ever seen in a Colt brochure and is still manufactured to the best standards on the production lines of Japan. Another classic in the making.

The Colt Age

Envision a flashy car, the type you may see the leading man in a film zoom through twisty Italian mountain roads in, with an excited long-haired blonde in the passenger seat. Envision a pop star automobile, with a shiny-hatted chauffeur driving his tattoo-wearing passenger past a horde of flashing press photographers. Chances are that neither of the automobiles that you have visualised in your mind are the Mitsubishi Colt Cleartec, however consider this – are you a global spy of intrigue? Are you the lead guitarist from a hard rocking heavy metal band? Or do you need a car which can get you around your neighbourhood, still look stylish and not break down on you half way to the south of France?

You possibly will not have noticed it, but the Mitsubishi Colt has become a classic car. Take the opportunity to think about this – there was clearly a time when the Rolls Royce Phantom III was just the newest car out there, when the Jaguar E-type had just rolled off the line. But this time has gone and these cars are inked into the records of history as classics. Likewise, while we were all occupied growing up the Colt has been there along with us, created with care and excellence since 1962.

Take a peek at the latest Colt brochure and you will see the principles which make a great car have been stuck to ardently for nearly fifty years. Efficient, economic, affordable and elegant, this car is the transport of choice for millions, while other supposedly ‘glamorous’ vehicles have come and gone, remaining the preserve of the obscenely wealthy and foolish.

Precisely what has to happen to elevate the Colt to the position of cult? It's possible it is already there and that we simply don’t realise, like a companion who you never knew you relied on so heavily until you needed someone and they were there.

If this is the situation then it cannot be long before the Colt will become an object of desire which we can all own. So why not feel like a rock star, a movie hero and a smart driver all in one and book yourself a Colt test drive now?

Operating Principle of 4-Cycle Engine

A 4-cycle engine completes the four stroke of intake, compression, expansion, and exhaust against 2 reciprocating motions of the piston, or while the crankshaft makes 2 rotations.

Basic Engine Components

An engine consists of several components, including :
