Problems solved by technology
[0002] In cold regions, since the engine is used in extreme temperatures, the engine object is subjected to a strong cold environment, causing the engine aluminum alloy object to be in a physical phenomenon of thermal expansion and contraction, and the cylinder object shrinks inwardly due to the cold. When starting, when the piston and the cylinder are in contact with the matcha, the shell shrinks due to the low temperature, which reduces the gap between the two, resulting in excessive compression and wear pressure between the piston and the cylinder. Leading to piston wear failure engine scrapped

The invention discloses a parallel type liquid heating device. The parallel type liquid heating device is installed in a passenger car and connected with an engine and comprises a combustion heating chamber and an internal circulation heating chamber which are communicated with each other. A fuel input pipe connected with a vehicle fuel tank is arranged on the outer wall of the combustion heating chamber, a combustion air inlet and a combustion waste gas outlet are further connected to the outer wall of the combustion heating chamber, and a low-temperature liquid input pipe and a high-temperature liquid output pipe are arranged on the outer wall of the internal circulation heating chamber. Original vehicle fuel oil conveyed into a heater combustion chamber through an independent electromagnetic oil pump is mixed with ambient air sucked in through a combustion-supporting wind wheel; mixed oil gas is ignited through an ignition plug, and high temperature generated by combustion serves as a heat source; the device is high in combustion efficiency, low in energy consumption and reliable in performance; and the structure is compact, size is small and maintenance is convenient.
Description
technical field [0001] The invention relates to the field of passenger cars, in particular to a parallel liquid heating device. Background technique [0002] In cold regions, since the engine is used in extreme temperatures, the engine object is subjected to a strong cold environment, causing the engine aluminum alloy object to be in a physical phenomenon of thermal expansion and contraction, and the cylinder object shrinks inwardly due to the cold. When starting, when the piston and the cylinder are in contact with the matcha, the shell shrinks due to the low temperature, which reduces the gap between the two, resulting in excessive compression and wear pressure between the piston and the cylinder. Lead to piston wear failure engine scrapped. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a parallel liquid heating device. This structure can reduce the excessive wear of the engine piston...
