    Abstract: A catalytic muffler for an internal combustion engine of a portable working tool, e.g. a chain saw or a trimmer, having a housing designed to be directly attached to an exhaust port of an engine. The housing further includes a front chamber and a rear chamber divided from each other by an intermediate baffle. The housing further having an inner housing having a first open end constituting the exhaust gas inlet located in the rear chamber. The inner housing includes a catalyst body through which essentially all exhaust gas flows when in use. A second open end of the inner housing is arranged in one of said front and rear chambers and the exhaust gas outlet of the muffler is arranged in the other chamber such that treated gas in use flows through at least one aperture in the intermediate baffle from one chamber to the other.

    Abstract: A water-cooled internal combustion engine E is provided with a cylinder block water jacket Jb, a cylinder head water jacket Jh, and an exhaust manifold passage 38 in which exhaust gas discharged from combustion chambers 26 through exhaust ports 28 collects. The exhaust manifold passage 38 is formed only in a cylinder head 21. The exhaust gas that has collected in the exhaust manifold passage 38 is discharged through an exhaust outlet of the exhaust manifold passage 38 from a cylinder head 21 into an exhaust passage 39 formed in a cylinder block C. The exhaust manifold passage 38 is surrounded by the cylinder head water jacket Jh, the cylinder block water jacket Jb and a discharge water jacket 80 for carrying cooling water from the cylinder head water jacket Jh and the cylinder block water jacket Jb to the outside of the engine body. The engine E provided with the exhaust manifold passage 38 does not require any assembling work for sealing the exhaust manifold passage 38 and hence the cost of the combustion engine E can be reduced. A wall defining the exhaust manifold passage 38 can be efficiently cooled by the cooling water that flows through the water jackets.

    Abstract: A start-up strategy for engine feedback control that utilizes a combustion condition sensor associated with only one cylinder. On starting and warm-up, only that one cylinder is feedback-controlled at all times. Under these conditions, the amount of corrected fuel supplied to the feedback cylinder is added to a fixed incremental amount of fuel that will be supplied to the remaining cylinders. This promotes smooth warm-up without backfiring or stalling and a quicker transition to all cylinder feedback control.

    Abstract translation: 用于发动机反馈控制的启动策略，其利用仅与一个气缸相关联的燃烧条件传感器。 在启动和预热时，只有一个气缸始终被反馈控制。 在这些条件下，向反馈气缸供给的校正燃料的量被添加到将供应到其余气缸的固定的增量的燃料。 这可以促进平稳的预热，而不会发生反燃或失速，并且更快地转换到所有气缸反馈控制。
