The CHRA Cartridge - The Heart of Your Turbocharger Your turbocharger is a highly efficient mechanism to increase your vehicle's power, performance, and speed. The Center Housing Rotating Assembly (CHRA) represents the main component in your turbo assembly and includes the compressor wheel, turbine wheel, and rotating shaft that houses the bearings. By compressing the air that flows into each cylinder, the CHRA increases air intake by about 50% and simultaneously allows more fuel into the cylinder. Additional fuel means bigger combustion a...

Can I Trust a Refurbished Fuel Injector? Your diesel engine hasn't been up to par lately. You suspect you need a new diesel engine fuel injector. Before you buy a replacement, let's look at the signs your engine is giving you that the fuel injector needs to be replaced. Signs of a Faulty Fuel Injector Fuel Leak. A leak could be caused by a worn or improperly maintained fuel injector. You may notice a sharp and pungent smell of fuel when you are driving, which would indicate a leak. Loud Idling Noise. Instead of the softer...

How to Find a Clogged Fuel Injector Diesel fuel injection is a key part of any diesel engine system. Diesel fuel injection parts are the parts that ensure the engine receives the correct amount of fuel at the correct time by delivering the fuel to the cylinders as a fine mist (so it is easier to burn). Keeping fuel injectors unclogged is critical to a functioning fuel-injected engine. If a fuel injector is clogged, it can't inject fuel, and you face a number of problems. These problems can manifest themselves in different w...

Comparing and Contrasting Four-Stroke and Two-Stroke Engines Both four-stroke engines and two-stroke engines utilize the combustion of fuel to harness the energy necessary to run their respective engines. If they are accomplishing the same goal through the same process, how different can they be? Let's take a deeper look into how four-stroke and two-stroke engines function. Four-Stroke Engines Inside a four-stroke engine, there is a crankshaft. Piston rods connect the pistons to the crankshaft, causing the pistons to move up and down with each turn...
