  • Patent number: 10662866
    Abstract: A diesel engine includes a cylinder head, a cylinder sleeve, a piston, an injector, and a combustion chamber. The top side of the piston includes an annular top surface, an annular collision belt and an annular cavity. The collision belt includes a collision surface, an upper guide surface, and a lower guide surface. An annular throat is formed between the upper guide surface and the cylinder head. The collision belt divides the combustion chamber into a headspace and a central portion. The volume of the headspace is more than three times of the volume of the central portion. A major portion of the fuel jet injected by the injector is directed into the headspace. The results are faster mixing of fuel and air and complete combustion in the combustion chamber, and a reduction of fuel consumption rate by 2%. A method for fuel distribution and combustion is also disclosed.

  • Publication number: 20190048369
    Abstract: Provided is a device for producing ultra-low sulfur biodiesel. The device for producing ultra-low sulfur biodiesel is a two-stage processing device, comprising a two-stage purification unit, a two-stage enzyme reaction unit, a two-stage distillation unit, and a decompression rectification unit. The present invention is green and environment-friendly, effectively and completely removing sulfur-containing impurities from the raw material, eliminating the attack of a sulfur-containing group in the synthesis process on fatty acids, and providing sufficient conditions for obtaining ultra-low sulfur content methyl esters in the product section.

  • Publication number: 20160363042
    Abstract: A combustion chamber of diesel engine. The diesel engine includes a cylinder head, a cylinder sleeve, and a piston. The cylinder head, the cylinder sleeve, and the piston form the combustion chamber. The combustion chamber includes a headspace; a central part; and a collision belt. The collision belt includes a collision surface, an upper guide surface, and a lower guide surface. The collision belt is configured to connect the headspace and the central part. The collision surface is an inclined surface, a convex surface, or a concave surface. The first tapered surface includes a second inclined surface, a second curved surface, and a third inclined surface; the second tapered surface includes a fourth inclined surface, a third curved surface, and a second concave surface; the first curved surface includes a second convex surface and a third concave surface.
