Bring The Heat Or Keep Your Cool – Engine Thermal Management
Vehicle manufacturers work to maximize cooling system efficiency to manage temperature while using less engine power.
Engine Bearing Supplier Q&A
It’s hard to believe that such small shell-shaped parts are so critical – manufacturers explain.
Greenspeed Research Sets World Landspeed Record For Diesel Trucks
Greenspeed Research broke the record for diesel trucks by reaching a speed of 219.411 mph at the 69th annual Southern California Timing Association Speed Week in Utah.
Engine Bearings Under Pressure
Engine bearings have to withstand punishing loads in today’s engines. Smaller displacements, turbocharging and higher horsepower ratings mean crankshaft and connecting rod bearings are being subjected to heavier loads. This has led to the development of some new bearing alloys and coatings that enable these parts to survive.
How Oil Change Habits Are Killing Turbos
Turbochargers are used to enhance an engine’s performance and optimize combustion. To achieve good and complete combustion in the engine, a mixture ratio of 2.2 lbs. fuel and approximately 33 lbs. air is necessary (stoichiometric fuel ratio). During turbocharging, the density of the intake air is elevated and the air volume increased.
The Engine Thermostat: Understanding Electronically Assisted Thermostats
The engine thermostat has been an important component in automotive internal combustion engines for almost a century. The engine thermostat helps to speed warmup and reduce cylinder ring wear. Today, the engine thermostat plays an important role in increasing engine combustion efficiency and reducing emissions. To accomplish that task, engine thermostat functions are controlled by the engine’s electronic control unit (ECU), ensuring precise regulation of temperature based on the engine’s loads.
Diesel Performance Head Gaskets
Head gaskets have a tough job sealing combustion pressures in diesel engines because of their high compression ratios and boost pressures. Diesel engines are typically low revving, high torque motors that are designed to last several hundred thousand miles.
Turbocharged 12-Valve Cummins Engine
Guys like Cody Helms prove that being competitive in diesel motorsports doesn’t have to be a pocket-emptying hobby.
