    Abstract: Cylinder head assemblies including a cylinder head and a piston are disclosed. The cylinder head includes: a recessed valve region including a first and second bulbous portion connected by a waist, the first bulbous portion accommodating an intake valve and the second bulbous portion accommodating an exhaust valve; an intake port passageway having a gradually contoured flowpath between an intake port and the intake valve in the valve region; and an exhaust port passageway having a gradually contoured flowpath between an exhaust port and the exhaust valve in the valve region. The piston includes a recessed region that substantially conforms to the recessed valve region of the cylinder head. Related overhaul kits and methods of making improved cylinder head assemblies are further disclosed.

    Abstract: A line of small internal combustion engines (50, 300, 400, 500, 600, 700), including twin cylinder engines (50, 300,400) and single cylinder engines (500, 600, 700). The engines each include a crankcase (52, 302, 402, 502, 602, 702), and one or more cylinder members (74, 306) attached to the crankcase, the cylinder members being separate components from the crankcase. A number of different crankcases are provided for various types of single and two cylinder engines, the crankcases having common mounting structure (72, 76) to which the cylinder members may be attached. Thus, the manner in which the cylinder members are attached to the crankcases is the same for each of the different types of crankcases. Two different types of cylinder members are provided, one having a side valve or "L-head" valve train (110), and the other having an overhead cam ("OHV") valve train (332). The cylinder members are therefore modular components which may be selectively used in a variety of different types of engines.

    Abstract: A small four cycle engine (10) is enclosed having a cylinder head assembly (12) which comprises a cylinder head (48) which cooperates with a cylinder block (16), and a rocker box (50) connected to the cylinder head (48) so as to define an air passage (64) therebetween through which air may pass. The cylinder head (48) has cooling fins (70) projecting into the air passage (64) between the head (48) and box (50) and aligned transversely to a line extending between the axes of the intake and exhaust valves (18, 20). The air passage (64) preferably extends between an intake port (66) and an exhaust port (68), and above an exhaust gas recirculation port (77). A pair of push rod tubes (78, 80) are integral with the rocker box (50) and extend between the box (50) and a crankcase (24) externally of the cylinder block (16). The engine (10) of the present invention also includes a cam tower assembly comprising a base member (86) and a pair of parallel shafts (32, 84) extending from the base member (86).

    Abstract: The aforesaid first breather passage (94) opens in the vicinity of the spring retainer (8f) for the aforesaid intake valve (14a) on the surface of the aforesaid cylinder head (8) which faces the aforesaid valve operating mechanism chamber (92) for the valve operating mechanism (74). The opening (8K,8s) of the said first passage (94) and the vicinity of the aforesaid exhaust valve (14b) are connected by a second breather passage (95). This second passage (95) comprises a groove (8p,8u) formed by cutting in the valve operating mechanism chamber surface of the aforesaid cylinder head (8), and a tunnel formed between an oil guide wall (8j) which goes up from the valve operating mechanism chamber surface of the aforesaid cylinder head (8) and the peripheral wall (8a) of the head. One end of this groove (8p,8u) connects to the opening of the aforesaid first breather passage (94).
