Driving a High Performance Vehicle in a Hot Climate
Posted: 21st May, 2018
Ever wondered what it’s like to drive a high performance car somewhere that’s hot? And we don’t just mean UK hot but really hot, pushing 40℃+ hot. Well, the initial experience is usually great. Sexy looking vehicle, plush interior and lovely cool air conditioned comfort. And it goes like a rocket too. Well, it does, for a bit.
After two or three 'rapid' starts, the engine will be getting very hot.
Now, we know what happens then. In modern engines, the ECU is constantly monitoring the onset of detonation. As the inlet air temperature rises and the knock limit is approached, the system retards the ignition to avoid detonation but this only increases the temperature still further. It also of course reduces the power produced.
The problem gets worse the longer high power is required and/or the ambient temperature is high.
The next line of defence for the engine is to inject excess fuel to cool the combustion and stave off detonation. This extra fuel is unburnt and completely wasted and goes straight out of the exhaust. As a last resort, the ECU simply turns the power down
...leaving the expensive supercar driving like a tame pussy cat.
This problem doesn’t just affect posh supercars though. Many vehicles operating in extremes of hot climate suffer from overheating and loss of power.
The best way to avoid this loss of power is to actively control the temperature of the inlet air. This is the value of our Active Charge Air Cooling system.
It is unique in that it can not only reduce the charge air temperature but also maintain it at a specified level. This has huge benefits in terms of achieving the full potential power of the engine and improving fuel economy. For engine designers it offers the chance to increase the compression ratio of the engine to deliver even more power and efficiency gains.
We know not everyone can afford or even wants a supercar. However, many people do need to run vehicles in hot climates - military and security forces, agricultural operators, exploration and survey teams etc.
Our system can help any internal combustion engine that suffers from overheating in extreme conditions.
We would love to show you how our system works and explore how we might help you maintain the power that your turbocharged engine installation is supposed to deliver, regardless of how hot it is. Get in touch here for more information or to set up a confidential discussion.
