  • Publication number: 20210332302
    Abstract: The present invention a mixed fuel suitable for diesel engines, which consists of the following components by volume percentage: 35% to 37.5% of diesel, 35% to 37.5% of ethanol and 25% to 30% of PODE, wherein the diesel is petroleum diesel having a cetane number not less than 48; the purity of the ethanol by mass percentage is not less than 99.5%; and, the PODE is a mixture of two fuels shown by molecular formulae CH3O(CH2O)3CH3 and CH3O(CH2O)4CH3. The use of this fuel is advantageous for emission reduction.

  • Publication number: 20210277842
    Abstract: The present invention discloses a cold start operation device and control method for a diesel engine in a plateau region under a low ambient temperature, allowing a starter to drive a piston to compress the low-temperature air, by using the heated air as the fresh inlet air to introduce it into the cylinder, so that the in-cylinder temperature at the compressing TDC is increased to obtain the ignition temperature, and finally achieving the cold start of diesel engines in plateau regions. The present invention avoids complicated preheating devices, and has simple structure and reliable performance, can achieve effective cold start in different low ambient temperature environments.

  • Publication number: 20190112815
    Abstract: In some aspects, deicer systems to distribute a deicing fluid along a roof of a building to limit ice dam formation can include: a pre-pressurized water source that provides pressurized water; a deicer solution source containing a deicer solution; a passive mixing system in fluid communication with the pre-pressurized water source and the deicer solution source, the passive mixing system being configured to combine the pressurized water and the deicer solution to form a deicer fluid; and one or more emitters configured to be disposed along the roof, the emitters being in fluid communication with the passive mixing system to receive the deicer fluid and dispense the deicer fluid along the roof. In addition, certain systems described herein can be run with an electric pump.
