Comments Off on Throttle Bodies

The throttle body is part of the internal combustion engine fuel system: it is designed to regulate the air flow into the combustion chamber.

The throttle body usually consists of a cylindrical or oval part that connecting the thermal unit (combustion chamber, cylinder head, piston and cylinder) with the outside. In this pipe there is the butterfly valve which regulates the flow of air: its working depends on the accelerator of the vehicle – the acceleration makes the valve open more thus allowing a greater flow of air. This is brought to the engine by depression, by the piston, by the carter in the four / two-stroke engines or by the turbocharger in the supercharged engines. Some throttle bodies are also equipped with an additional pipe which, going past the primary valve, acts as a pipe for idle speed and is regulated by an electric motor (so called “idle motor”): this regulates the flow of

The EGR valve "Exhaust Gas Recirculation" has the assignment to recirculate a part of the unloading gases released by the motor ("exhausted gas") and re-send them to the intake manifold in a percentage that oscillates among 5% and the 15% of the total one of the gases produced by the car. The purpose is to defeat the pollutants produced by vehicles : a noble goal surely, that goes in the direction pursued by the European states which try to limit the diffusion of the environment of the NOxes (nitrogen oxides), very polluting to tall pressures and temperatures. This recirculation of the exhausted gases in the phase of unloading happens thanks to the signals given by the ECU(electronic control unit) to a solenoid valve. This last one has the function to close and open itself and regulates the passage of the gases through an exchanger which lowers the temperature of gases and puts them again in the intake manifold. Once arrived inside ,are remixed to the inhaled air and produces combustion. Unfortunately the malfunctions to this valve are frequent, due mainly to the accumulation of dirt caused by the passage of the unloading gases. The problem can be especially noted in cases of diesel vehicles used for short distances and in this c [...]

Dump Valves

Comments Off on Dump Valves

The pop-off valve is also known as air recirculation valve a or dump valve . It was born to eliminate the water hammer due to the sudden increase in pressure in the duct between the compressor and the throttle body when, with the engine under load and with turbo at high revs, the accelerator is removed or when the butterfly on the throttle body is closed . The air from the delivery duct after the compressor is recirculated in suction before the latter.

The free discharge solutions are only a free interpretation not supported by any technical reason. Of course the recirculated pop off loses the noise that many people enjoy.

For this product category SAITO proposes the pop-off valve that is mounted on the turbo 49373-03012 (OE 55243431.01) for Fiat 500, Panda, Punto, Lancia Ypsilon, Alfa Mito with Fiat SGE engine –

TD04L Turbocharger thermal blanket Installed directly onto the exhaust housing of your turbo and provides very effective insulation. It is sized for TD04L turbos. Thermal insulation has some benefits including: - a cooler engine bay, due to the drop in ambient heat, giving reduced intake temperatures; - improved turbo performance due to the retention of heat within the exhaust housing Turbocharger thermal blanket Installed directly onto the exhaust housing of your turbo and provides very effective insulation. It is sized for most common T25 - T3 - T4 - T6 turbos. Thermal insulation has some benefits including: - a cooler engine bay, due to the drop in ambient heat, giving reduced intake temperatures; - improved turbo performance due to the retention of heat within the exhaust housing In the presence of turbochargers equipped with an actuator, the installation must always be evaluated so as not to compromise the correct functioning of the valve. Thermal Insulating Bandage Kit + Stainless Steel Clamps Material: the insulation tape is made of basalt fiber through a special weaving process.

Its proper functioning protects the compressor wheel

Comments Off on Blow-By Filters

The engine is a system of moving mechanical parts and pressure is generated internally due to its dynamism. The only way to reduce such pressure is to create a vent to the outside. Unfortunately however, the exhaust fumes of the engine are carcinogens because they contain combustion residues and oil molecules. A new engine will have low pressure in the sump because the seal between pistons and cylinders will be excellent being ensured by new and not worn out piston rings. With time and use, the seal of the cylinders will be reduced thus letting in more pressure inside the engine and creating a greater quantity of gas. In order to reduce pollution, these fumes are put in circulation towards the intake of the engine or between the air filter and the compressor so as to burn all the polluting molecules.

To prevent damage to the compressor wheel, filters and settlers have been installed in

Oil Inlet Pipes

Change it every time you replace the turbocharger!

Comments Off on Oil Inlet Pipes

Whenever it is necessary to replace the turbocharger, it is advisable to analyze and consider the replacement of all the components close to it which help it work properly. The oil inlet pipe is one of them, being responsible of the lubrication necessary to the turbo to avoid seizure. Unfortunately the importance of this small component is often underestimated by professionals. In fact, the clogging of the oil inlet pipe, particularly when dealing with some specific ones that suffer from this defect, represents one of the first causes of failure of the turbo itself. It is strongly recommended to replace the oil inlet pipe every time a turbocharger is replaced.

Exhaust Risers

Comments Off on Exhaust Risers

Particularly when the inboard marine engine is close to the waterline, it is often necessary to include the so-called “exhaust riser”, a component connected directly to the exhaust manifold. Normally the riser has an external over-wrap where the water that surrounds the exhaust gas pipe circulates, guaranteeing the cooling of the entire circumference of the pipe itself. The exhaust riser of a marine engine aims to guartantee the collection, the mixing and the engine cooling water and fuel gas expulsion.

Exhaust manifolds and risers are therefore essential components for the correct operation of the direct or indirect cooling system of the inboard marine engine.

For all the most common inboard marine engines – Volvo Penta, Yanmar, Iveco Aifo, Mercury Mercuiser just to name a few – SAITO, through its commercial partner SAILOG, sells exhaust manifolds and risers, pipe elbows, bends, dual chamber exhausts and heating exchangers all of them made of stainless steel for deep
