Autobiography Kee GS5 1.8T AWD models were starting at the Guangzhou Auto Show, opened its own brand Chi Chuan's "T era."
In the automotive industry, mainly in environmentally friendly energy trend, small-displacement turbocharged engine technology also have to go on the road, GT2871 Turbo and a small displacement of the economy is also valued by many owners of a condition. Chi Chuan GS5 1.8T four-wheel drive version of the model as a positioning range at 10 ~ 20W and has a turbocharged engine SUV models, with very epoch-making significance. Lack of energy-efficient economy without manipulation, following Cheng Zhuanqi brand has always been the quality of security. Chi Chuan GS5 1.8T focus position can be described as a deserved.
Chi Chuan has a world-class luxury car brand Alfa Romeo pedigree is well known things, then as a core course, as it should have a high foundation started. As has been applied on cars Alfa Romeo 156 engine, has been a strong driving force, known for rugged durability features. Today, after Guangzhou Automobile Chi Chuan further improvements to upgrade the redesigned cylinder head and ignition system, and improve the emissions and VVT control, and adding a lot of high technology, this engine's performance to the next level.
The turbocharger is actually an air compressor, compressed air to increase the amount of intake air. It is the use of engine emissions inertia momentum to drive a turbine room turbine, the turbine has led coaxial impeller, the impeller pressure feed pipe sent by air cleaner air, making it into the cylinder supercharged. GT2860 Turbo When the engine speed increases quickly, the discharge speed of the exhaust gas turbine rotational speed is synchronized with faster, more impeller to compress air into the cylinder, pressure and density of the air increases to burn more fuel and adjusting the amount of fuel corresponding increase in engine speed , it is possible to increase the output power of the engine.
A closer look, Chi Chuan GS5 1.8T turbocharger with water-cooled, from the world's number one supplier of turbochargers - Borg Warner is the latest generation of water-cooled turbocharger.
Why should increase the water-cooled exhaust side because, generally with high temperature materials cast (usually high nickel alloy steel casting);? Suction side, generally cast aluminum material. The key components of the turbocharger bearing. This form is named according to the lubrication of the bearing is called "full floating bearings", high working speed, harsh working environment. Therefore, to ensure the lubrication is important. If oil supply due to low oil pressure led to slow, it will damage the bearings causing the turbocharger failure. In a normal engine start is not such a failure, but if the engine oil and oil filter replacement first starts, it will produce oil supply slow phenomenon, so the lack of oil lubricated bearings. In this case, after starting to about 3 minutes idling operation is not directly improve the speed of the turbocharger to the startup speed. Also, do not make the engine stopped immediately after the high-speed and uphill, to make the engine continues to idle one minute or so, so that continues to idle turbocharger bearings are not short of oil.
Old turbocharger, oil cooling only, in order to ensure proper cooling of the turbine, often need to stop idling more than 3 minutes to turn off the engine. BorgWarner GS5 using the latest generation of water-cooled turbocharger, greatly reducing the cooling time, but from the perspective of engine maintenance, please idle for at least 1-2 minutes better.
