Burning vegetable oils in direct-injected diesel engines leads to nozzle and combustion chamber coking and eventually to engine damage. Because typical durability tests to detect coking tendencies of fuels are expensive, a one-cylinder diesel engine was instrumented and automated to enable external detection of engine coking in only 5 h. The heat release pattern revealed shifts to later burning as coke accumulated in the engine, but exhaust emissions showed little correlation with coke accumulation.
