A number of fuel-injected gasoline engines were subjected to 300-hour cyclic-endurance tests to validate a new production facility.
Oil consumption, blowby, and other normal performance parameters were measured and recorded throughout the test. In addition, performance tests, valve stem height, cranking compression, leakdown, and high-pressure nitrogen leak tests were performed at periodic intervals. A distributed digital process control system was used to operate the engine through the test cycle by precisely controlling both engine speed and dynamometer load to maintain test requirements. Data acquisition was accomplished using a Hewlett Packard 1000 Series computer. Fuel for all testing was Indolene Clear, a reference grade of gasoline.
In addition to actual engine testing, the SwRI® technical staff was responsible for installation and maintenance of engine support electronics equipment, heads-up displays, and sensors. Engine failure analysis and repairs were conducted when required.
