It is becoming hard to come across a diesel that is not using a turbocharger. It can be difficult to figure out what turbocharger is right for your needs and vehicle. At Diesel Injection Service, we have an experienced staff that is able to answer any of your questions ranging from what turbocharger is best for you, to the differences between the dealers.
We stock a large range of turbochargers from the leading brands. If you need it, we will be sure to find it for you here at Diesel Injection Service.
Turbo is our middle name and we show it with products from Cummins®, KKK®, Holset Turbochargers®, Caterpillar®, Schwitzer®, Garrett®, Borg Warner Turbo Systems® and Detroit Diesel®.
How a Turbo System Works
Engine power is proportional to the amount of air and fuel that can get into the cylinders. All things being equal, larger engines flow more air and as such will produce more power. If we want our small engine to perform like a big engine, or simply make our bigger engine produce more power, our ultimate objective is to draw more air into the cylinder. By installing a turbocharger, the power and performance of an engine can be dramatically increased.
So how does a turbocharger get more air into the engine? Let us first look at the schematic below:
1 Compressor Inlet
2 Compressor Discharge
3 Charge air cooler (CAC)
4 Intake Valve
5 Exhaust Valve
6 Turbine Inlet
7 Turbine Discharge
The components that make up a typical turbocharger system are:
The air filter (not shown) through which ambient air passes before entering the compressor (1)
The air is then compressed which raises the air’s density (mass / unit volume) (2)
Many turbocharged engines have a charge air cooler (aka intercooler) (3) that cools the compressed air to further increase its density and to increase resistance to detonation
After passing through the intake manifold (4), the air enters the engine’s cylinders, which contain a fixed volume. Since the air is at elevated density, each cylinder can draw in an increased mass flow rate of air. Higher air mass flow rate allows a higher fuel flow rate (with similar air/
