摘要：A high-energy multispark ignition system with a single discharge capacitor was designed and developed. The ignition system was verified to be capable of releasing high ignition energy. The cold start and partial-load test at 6 degrees C ambient temperature were conducted on a two-stroke spark ignition heavy fuel engine with air-assisted direct injection. The results showed that compared to the original magnetoignition system, applying the 5-times multispark ignition approach with the new ignition system is able to successfully solve the cold start problem of the heavy fuel engine. Under the partial-load condition, increasing the number of ignitions enhances combustion in the cylinder. Four-times ignition is better than 2-times ignition with the ignition timing angle between 10 degrees and 20 degrees CA BTDC, improving the power output, fuel economy, and HC/CO emissions performance. The effects of multispark ignition gradually become small with the ignition timing angle advanced to 30 degrees CA BTDC.
