BMW M4 GTS

MoBlizt - Today more and more technologies are developed to improve the performance of the car. One row of the latest technology that is being talked about is water injection or water boost applied by BMW M4 GTS. Yes, water or air, you did not misread. Sounds weird huh? I felt so when I first heard this term. Normally, we always avoid the engine from water bath for risky cause damage, this was actually injected water.

Quiet, of course, the water is not injected directly into the combustion chamber, but the pure water that is distilled is sprayed on the intake manifold to reduce the temperature of the intake manifold. With falling temperatures, the air content can be more compressible and compression in the combustion chamber can be increased. This will certainly make the combustion becomes more efficient, which means more power optimally. Parties Bosch explained that the actual temperature reduction technology like this has been used before, but it will use gasoline instead of water. So in addition to diletupkan sprayed gasoline in the combustion chamber, there is also a small portion of gasoline is sprayed only to be evaporated that the temperature drops.

Increase Power, Reduce Emissions
Bosch as a pioneer in this technology, the first to embed water boost the BMW M4 GTS to boost performance and increase efficiency. Claims Bosch, power can be increased to 5% without having to change or improve the capacity of the combustion chamber fuel spray, it also increases the efficiency up to 13% during acceleration or on a long trip. By using water injection, 3,000 cc engine TwinPower Turbo 6-cylinder can produce power up to 500 hp and torque up to 600 Nm. Another advantage of this technology is to reduce the CO2 in flue gas by 4% as a result of combustion in the engine of effective and efficient.

Then where steam used it come from? Distillation water injection M4 GTS taken from water being stored in tubes of five liters (the amount will vary) situated around the rear trunk. When the water runs out, the engine will still be in operation, only bursts of energy is reduced, and the machines became more extravagant. For the treatment of this water injection technology, the vehicle owner should check the amount of water remaining on a regular basis, or to recharge every 2,896 km.

The plan BMW not only restrict this technology to a dedicated track car, but also will put them on a mass product starting in 2019 later. The form will not be much different from the water injection Bosch alerts mounted on the M4 GTS today.
