Abstract

The invention relates to the technical field of diesel engines, in particular to a diesel engine and a piston. The diesel engine comprises a shell, a rotating shaft is rotatably connected to the position, close to the lower end, of the inner wall of the shell, a flywheel is fixedly connected to one end of the rotating shaft, a connecting rod is rotatably connected to one end of the flywheel, and the piston is movably connected to the upper end of the connecting rod; an air suction pipe is fixedly connected to one side of the outer surface of the upper end of the shell, an exhaust pipe is fixedly connected to the other side of the outer surface of the upper end of the shell, and a cleaner is fixedly connected to the interior of the exhaust pipe. When waste gas in the diesel engine is exhausted through the exhaust pipe, the waste gas is filtered through the activated carbon filter cotton, the activated carbon filter cotton can adsorb harmful substances and pungent diesel oil smell in the waste gas, the problem that the harmful substances in the waste gas pollute air is solved, and the first fan blades can be driven to rotate when the waste gas is exhausted; and when the brush rotates, ash residues attached to the surface of the activated carbon filter cotton can be cleaned away.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a diesel engine and a piston. Background technique [0002] Diesel engine is an internal combustion engine that uses diesel as fuel. Diesel engine is a compression ignition engine. When the diesel engine is working, it inhales the air in the cylinder of the diesel engine and is compressed to a high degree due to the movement of the piston, reaching a high temperature of 500-700°C. Fuel is sprayed into high-temperature air in the form of mist, mixed with high-temperature air to form a combustible mixture, which is automatically ignited and burned. The energy released during combustion acts on the top surface of the piston, pushing the piston and converting it into mechanical work of rotation through the connecting rod and crankshaft. [0003] Exhaust gas produced by diesel engines in the prior art after compression ignition will be discharged into the air, sometimes due to ...
