Valves, Valve How it Works

Valve located on the cylinder head on each vehicle is shaped like an umbrella. Valve is divided into 2 work, the first is the valve and the second entry is the waste valve. Valve in its function is to include a mixture of air and gasoline that have been shaped into a cylindrical fog machine. While waste valve is the valve that serves to remove the combustion gases after the piston compress. Each vehicle has a number of valves different. In the small cars made in Japan tahun80an, usually the number of valves in each cylinder there are 3 valve. However, today's cars are now adopted at 4 valves per cylinder. This is done to enhance the volumetric efficiency so that utilization can be more effective fuel and power for the greater dihasilkanpun cylinder engine together. So that when a 4-cylinder engine has a valve in the number and total waste of 16. as well as motors, the motors were cc usually have 4 valves. 2 in and 2 waste. Valves are usually made of heat resistant steel and stainless (Stainless Steel). We're doing the compression, the valve serves to close the hole or channel in the cylinder. At the end of combustion, waste valve to drain immediately open the rest of the combustion gases to the exhaust manifold. After the disposal process is complete, the piston will do steps suction and suction-valve was opened to include a mixture of air and gasoline that has clouded towards the engine cylinder. Each valve of a cylinder to open and close movement once for every two crankshaft rotation (crankshaft).

Berkonstruksi engine valve on the side, these valves are driven by a pressure valve is driven by the boss. While the engine valve system that applies above (SOHC / DOHC), a pressure valve and pressure valve stems. Having raised so terlepasdari place holder, the valves are returned to their original position by a spring. At the time of opening, the valves will be lifted from the holder of 5/16-3/8 inch. Also the valve can be said to work hard. Like, if the engine spinning 7500 rpm, the valve opened and closed more than 60kali/detik. If the engine was encouraged to 10,000 rpm, the valve is forced open and close to more than 80 times / second. Valve temperature can reach 700 degrees Celsius

iVTEC

Two engines are on the type of Integra cars in 2002 we combine a number of innovative display that is designed to produce a combination of performance, efficiency and low fuel. The most important thing is the system of Honda VTEC valve control - a technology that combines VTC (Variable Timing Control) - a technology move a valve adjustment time which carries fuel room - by using the VTEC system - is changing appointment, setting and duration of engine valves.
The results of this technology is a big horsepower and amazing also accompanied by the use 1099648322bsecara fuel economy and environmentally friendly. Another advantage of this system is the position of the engine has been rotated 180 degrees from a position closer to the conventional machine expenditure pipe (exhaust manifolds) with pipe catalyst to reduce emissions when the engine starts. Integra VTI's engine is made entirely of aluminum with the strength 2.0-liter (2,000 cc) that uses 16 valves, pipe two levels of income, and iVTEC system that produces 160 horsepower at 6.500 rpm and 191 Nm torque at 4.000 rpm. Integra Type R engine also has features to increase your cars power 1099648322cmenjadi 200 horsepower at 7.400 rpm and 193 Nm torque at 6.500 rpm. In accordance with Honda's commitment to environmental sustainability, both types of machines have been eligible low emission vehicle II levels that will be applied in the United States in 2004.

IVTEC Valve Control System
Integra Type of car we dedicate the 2002 edition of the latest version of the VTEC system, which is iVTEC - a VTC system combined with the VTEC that provides fuel room settings in turn. In addition to the usage of the level of fuel economy, this iVTEC system also reduces the level of exhaust emissions.

VTEC (Variable Timing and Lift Electronic Control)
Innovative VTEC system is able to regulate the duration of the appointment and the opening of the valves that help the engine torque at low rpm and high rpm power is amazing. At lower rpm levels, VTEC set the time and the appointment of the valve for optimum cylinder filling and use of fuel-efficient. Coupled with the valve timing of high and asymmetric lifting - which produces the effect of rotation in the burning room - the end result of this system is the increased speed and increased fuel burning power. With increasing rpm, VTEC engine turned into a burning room which has a high lift and duration which helps increase the engine at high rpm. Integra is a new type using two kinds of VTEC - an extra-efficient versions for the type of VTI and high power versions for the type of R. VTI engine with 118 horsepower VTEC introduced a new version that can increase energy and reduce emissions. Another advantage of this system is the use of two drivers on each leg pair of suction valves (intake valves) compared with the conventional three-leg system. At low rpm, only one valve is fully open and vice versa, at high rpm both valves open. Integra Type R at 147 horsepower, also found the same VTEC system with the NSX type, namely the three legs of varying force and duration of the appointment of two suction valves and the thrower to push the maximum energy.

VTC (Variable Timing Control)
IVtec The new system introduces fuel system of leg room (cam shaft) in VTC VTEC rooms capable memfasekan fuel continuously in the overall power of the engine block. At the rpm increases, a leg drive VTC - which is governed by a unit set by the engine of the car - forward or rewind the fuel leg room - as far as 50 degrees that directly optimize the increased engine power and emission reduction. During normal operation, the intake camshaft timing is almost a full point when the vehicle is still and will further stabilize the movement of idle emissions while reducing expenses. Along with increasing rpm, the intake camshaft is growing, opening the valve earlier exploiters at the same time facilitate the overlap of the valve. The system provides functionality in fuel economy and further reduction of exhaust emissions. To raise additional power throughout the rev range, the intake camshaft is continuously differentiate the amount of advance or retard and adjustments directly to provide additional power as desired by the driver.

Tutbocharger and the supercharger

Tutbocharger and the supercharger is a separate device on the machine that is useful to increase the air supply needed by the engine combustion process. In other words the device is a turbine compressor to suck air from the outside and the air pressure had to channel the engine intake system. The difference between the two is the source driving the turbine rotation.

Turbocharger or a close called turbo has two turbines connected in one axis. Secondary turbine serves as a 'wheel' driving energy derived from 'blowing' air remaining combustion engine. This is a working windmill turbines rotate the main compressor.

Being able to move freely, the turbine compressor can be turned up more than 70.000rpm and air pressure can produce very large. Hence, this device was given passes to the valve by air pressure generated is not excessive.

If the turbo rely on the rest of the combustion gas pressure, turning the turbine or compressor supercharger engine torque advantage. Since the machine rounds generally just 'play' is less than the pressure 7.000rpm produced not sedahsyat turbocharger.

Therefore turbo engine is not advisable to immediately shut down when finished digeber at high speed. When the machine is switched off automatically immediately halt oil supplies, and it was turbo still spinning fast due to inertial forces which are still stored.

Generally paired turbo engine enhancements that are named turbo timer to keep alive the engine while the ignition key while revoked. The goal is to provide opportunities to the turbine in the turbocharger spins reduced to idle condition.

Because the device is connected to the turbo exhaust gas channel which is the source of heat, the temperature of the inhaled air in the intake manifold to increase participate. And if the temperature of hot air to the oxygen molecule tenuous and thin.

In a modern turbo engine is the device inserted between the turbo intercooler and intake manifold to reduce re-heat temperature to oxygen become more tightly.

To illustrate how powerful this tool is boosted power, in the era of turbo triumph at Formula 1 race, the engine could 1.600cc capacity to produce 1200 hp!
