Engine Hot Test

 As a premier engineering firm that supplies customtest equipment, Wineman Technology delivers cost-effective and highly configurable engine hot teststands for major OEMs and engine component manufacturers !nli"e proprietary, loc"ed do#n solutions,#e use commercial off-the-self $%OT&' hard#are and soft#are to create reliable, state of the art enginetest cells #ith easily replaceable or upgradable components #hile achieving best in class functionality

What is Engine Hot Testing?

Typically engine hot testing is performed to(

• )etermine fuel efficiency and drivability, #hich may include torque-speed performance test under

steady-state and transient conditions

• Evaluate the quality of production through periodic audit testing

• *ain further "no#ledge about the engine itself via engine mapping e+ercises or development of

multidimensional input-output maps among different engine variables $eg a map from inta"emanifold pressure and engine speed to inta"e air flo# rate'
