Engine Testing For Research and Development
Research and Development (R&D) activities on engines at automobile OEMs have necessitated sophisticated engine test stands. Automobile OEMs are usually interested in developing engines that meet the following threefold objectives:
- to provide high fuel efficiency
- to improve drivability and durability
- to be in compliance to relevant emission legislation
Consequently, an R&D engine test stands allow for a full-fledged engine development exercise through measurement, control and record of several relevant engine variables.
Typical tests include ones that:
- determine fuel efficiency and drivability: torque-speed performance test under steady-state and transient conditions
- determine durability: ageing tests, oil and lubrication tests
- determine compliance to relevant emission legislations: volumetric and mass emission tests over stated emission test cycles
- gain further knowledge about the engine itself: engine mapping exercise or development of multidimensional input-output maps among different engine variables. e.g. a map from intake manifold pressure and engine speed to intake air flow rate.

Famous quotes containing the words engine, testing, research and/or development:
“Industrial man—a sentient reciprocating engine having a fluctuating output, coupled to an iron wheel revolving with uniform velocity. And then we wonder why this should be the golden age of revolution and mental derangement.”
—Aldous Huxley (1894–1963)
“Now I see that going out into the testing ground of men it is the tongue and not the deed that wins the day.”
—Sophocles (497–406/5 B.C.)
“If politics is the art of the possible, research is surely the art of the soluble. Both are immensely practical-minded affairs.”
—Peter B. Medawar (1915–1987)
“Sleep hath its own world,
And a wide realm of wild reality.
And dreams in their development have breath,
And tears, and tortures, and the touch of joy.”
—George Gordon Noel Byron (1788–1824)
