This then generates increased mechanical power and overall efficiency improvement of the combustion process. A turbocharger is a small turbine that sits between the engine and the exhaust. The compressor also consists of two parts: the compressor wheel (5) and the compressor housing (6). You consent to our cookies if you continue to use our website. How does a turbocharger work? A Mazda RX-8 rotary coupe fitted with an aftermarket turbocharger system. The energy from the exhaust gas turns the turbine wheel, and the gas then exits the turbine housing through an exhaust outlet area (4). This is the reason why many auto manufacturers are choosing to turbocharge their vehicles. Exhaust gasses go through the turbine and spin it; the turbine rotates and sucks the ambient air from the other side and forces it into the throttle body. A turbocharger is an exhaust-driven mechanical device that boost engine power by pumping more air into the engine. Therefore, the engine size can be reduced for a turbocharged engine leading to better packaging, weight saving benefits and overall improved fuel economy. Information about the device's operating system, Information about other identifiers assigned to the device, The IP address from which the device accesses a client's website or mobile application, Information about the user's activity on that device, including web pages and mobile apps visited or used, Information about the geographic location of the device when it accesses a website or mobile application. A significant difference between a turbocharged diesel engine and a traditional naturally aspirated gasoline engine is the air entering a diesel engine is compressed before the fuel is injected. The compressor wheel is attached to the turbine by a forged steel shaft (7), and as the turbine turns the compressor wheel, the high-velocity spinning draws in air and compresses it. Turbocharger lag (turbo lag) is the time required to change power output in response to a throttle change, noticed as a hesitation or slowed throttle response when accelerating as compared to a naturally aspirated engine.This is due to the time needed for the exhaust system and turbocharger to generate the required boost which can also be referred to as spooling. Search our solutions database or contact Cummins Care via phone or online form. When air is compressed the oxygen molecules are packed closer together. A turbocharger (also exhaust gas turbocharger) uses the energy that is lost by the exhaust gas of a reciprocating engine, profitable for driving the cylinder. How does a supercharger work? How a turbocharger works The basic idea is that the exhaust drives the turbine (the red fan), which is directly connected to (and powers) the compressor (the blue fan), which rams air into the engine. The compressor housing then converts the high-velocity, low-pressure air stream into a high-pressure, low-velocity air stream through a process called diffusion. These are connected by a shaft, so turning the turbine wheel will turn the compressor wheel. These are also respectively known as the ‘cold’ side and the ‘hot’ side. This increase in air means that more fuel can be added for the same size naturally aspirated engine. A turbocharger is made up of two main sections: the turbine and the compressor. As fuel in the engine is burnt, exhaust gasses are forced out of the engine at high pressure, down a snail-shaped tube to spin the turbine.
