    摘要： Disclosed is a piston ported two-stroke compression ignition internal combustion engine comprising: a cylinder having a fixed closed end, and a piston for reciprocation within the cylinder, wherein the closed end of the cylinder and the piston together define a combustion chamber therebetween; at least one heater to heat the combustion chamber; and a controller to control the heater to heat the combustion chamber when the controller determines that a temperature of the combustion chamber has fallen below a threshold temperature during reciprocation of the piston within the cylinder.

    摘要： A leakage detection device detects leakage in a PCV passage that at least includes a scavenging line that communicates between a crank chamber of an engine and a portion of an intake passage of the engine that is on a downstream side of a throttle valve and a fresh air line that communicates between the crank chamber and a portion of the intake passage that is on an upstream side of the throttle valve. The leakage detection device includes a pressure measurement, a first valve and a leakage determination unit. The pressure measurement unit measures pressure in the PCV passage. The first valve opens/closes the fresh air line. The leakage determination unit determines presence or absence of leakage in the PCV passage on a basis of the pressure in the PCV passage at a time when the first valve is closed.

    摘要： There is provided a breather device for an engine and capable of suppressing forming of separated oil into mist again. The breather device for the engine includes an oil filter chamber at a midpoint of a blow-by gas passing route and an oil filter housed in the oil filter chamber. The oil filter chamber is partitioned with a partition wall into an upstream filter chamber and a downstream filter chamber arranged in a front-back direction, the filter is formed by an upstream filter and a downstream filter, the upstream filter is housed in the upstream filter chamber and the downstream filter is housed in the downstream filter chamber, respectively, and a side gas expansion chamber is provided beside the oil filter chamber so that blow-by gas flows from the upstream filter into the downstream filter through the side gas expansion chamber.
