Specific implementation mode
The utility model content is described in detail with embodiment with reference to the accompanying drawings of the specification：
It is a kind of embodiment schematic diagram of small-sized single cylinder water-cooled diesel engine provided by the utility model as shown in Figures 1 to 4.
A kind of small-sized single cylinder water-cooled diesel engine, it includes that body 1, cylinder jacket 2, cylinder head 3 and external water cooling are followed
Ring channel；
2 periphery of cylinder jacket is equipped with water(-cooling) jacket, is distributed with cooling duct 3-1 in cylinder head 3, the outlet end of water(-cooling) jacket with
The input end of cooling duct 3-1 is connected, and the outlet end of cooling duct 3-1 is equipped with thermostat 4；
Water-cooling circulating channel includes partial circulating 5 and systemic circulation 6；The partial circulating 5 is connected to 4 first exit end of thermostat
Between water(-cooling) jacket input end, and its transfer passage is equipped with power pump housing 5-1；
In the present embodiment, the systemic circulation 6 be connected to 4 second outlet end of thermostat and power pump housing 5-1 input end it
Between, and systemic circulation 6 is equipped with cooler 6-1.The operation of two cycles can be realized by a power pump housing 5-1.
In another embodiment, the systemic circulation 6 be connected to 4 second outlet end of thermostat and water(-cooling) jacket input end it
Between, and systemic circulation 6 is equipped with cooler 6-1.It needs separately to set power pump housing progress water cycle driving in the systemic circulation 6.
Thermostat is the valve for controlling coolant flow paths, is a kind of automatic temperature-regulator, usually contains the temperature module,
