The futureĪs car engines get smaller, automakers will want to eke out more gains from them.Įvery little bit helps when engines downsize. Too much water in the cylinder could result in blown heads, shattered pistons and a very, very bad time for you. In addition, the water tank must be topped up every 3000km or so, so you must keep an eye on it.Īlso, engine damage can occur if too much water is pumped in. Port fuel injection cars no longer exempted by VES
That involves a lot of time in getting it right, otherwise you negate the benefits of water injection. That’s because your engine is programmed to run on a specific air-fuel ratio, so introducing water injection will likely mean reprogramming your motor. What are the limitations of water injection?įirstly, technology like this can’t simply be retrofitted to any engine. The BMW M4 GTS is so far, the only production car to make use of water injection.įor the same compression, it nets you a more complete burn and therefore reduces the pollutants coming out from your engine.Īlso, it means that you need to burn lesser fuel to get the same power output, translating into better fuel economy. Having a denser air-fuel mix enter the combustion chamber translates to increased performance.Īs a reminder, internal-combustion engines love sucking down cool, dense air because it reduces the likelihood of knocking. That cools the intake air, making it denser (higher volumetric efficiency), preventing knocking, or premature detonation of fuel. In a car, water injection happens right before the intake valve. In modern cars, water injection won’t necessarily help you get out of a dogfight-slash-traffic light grand prix, but it can give you a more reliable engine. The P-47 Thunderbolt and P-51 Mustang both had water injection to briefly increase their power outputs.ĭirect injection engine: Does it have more carbon buildup? It has its roots in World War 2 fighter aircraft. Water injection – also called “anti-detonant injection” – is a technology that is claimed to reduce both fuel consumption and CO2 emissions while boosting engine performance. It’ll take a few years for it to trickle down to our bread-and-butter models, so let’s take a look at what benefits it brings. Furthermore an iBooster GEN1 connector kit is available and ins and outs for wiring can be found in the Wiring the Tesla iBooster blogpost. In fact, only the BMW M4 GTS in recent memory appears to have this tech. A 3mm mild steel GEN1 Tesla iBooster weld adapter is available. In reality, that’s a pretty apt description.īut not every car has this technology. Water injection sounds like the stuff of science fiction: squirt a jet of vapourised water into the engine to get more power! An illustration of Bosch WaterBoost technology inside an engine.
