Abstract: A method of operating an internal combustion engine includes moving an exhaust valve to a first open position to enable an exhaust product to flow through an exhaust port of the internal combustion engine. The method also includes maintaining the exhaust valve at the first open position for a predetermined time period. The method also includes moving an intake valve to a second open position during the predetermined time period to enable an intake product to flow through an intake port of the internal combustion engine. Additionally, the method includes preventing at least a portion of the intake product from flowing through the exhaust port during the predetermined time period with a first blocking member and a second blocking member.

Abstract: A method of operating an internal combustion engine (100) includes moving an exhaust valve (140) to a first open position to enable an exhaust product to flow through an exhaust port (152) of the internal combustion engine (100). The method also includes maintaining the exhaust valve (140) at the first open position for a predetermined time period. The method also includes moving an intake valve (136) to a second open position during the predetermined time period to enable an intake product to flow through an intake port (144) of the internal combustion engine (100). Additionally, the method includes preventing at least a portion of the intake product from flowing through the exhaust port during the predetermined time period with a first blocking member (180) and a second blocking member (176).

Abstract: In a multi-mode, 2-stroke/4-stroke internal combustion engine operation, by switching the engine stroke from 4-stroke operation to 2-stroke operation so that the combustion frequency is doubled, doubling of the engine power is achieved even at the same work output per cycle. In order to meet the demand of extremely high power, the engine operates in 4-stroke boosted SI operation transitioned from 2-stroke HCCI operation at pre-set level of power and crank speed requirements. By combining the multi-stroke (2- stroke HCCI and 4-stroke HCCI) and multi-mode operation (2-stroke HCCI and 4-stroke boosted SI operation), full load range and overall high efficiency with minimal NOx emission are achieved.
