Denn: No. I am saying the weight will reduce its efficiency that's all. Reduce from what to what? I don't know |

takenadoh: Making an engine block stronger with say additional 10kg of alloys would in no way reduce the efficiency if it produces more hp/torque or has a better MPG overall. All these would have been put into consideration at the basic level of engine design. One of the points given in the article is a leaner burn which implies lesser fuel consumption for same or more power.. This engine from all indications would be more efficient rather than less |

Denn: Okay you don't get it. I rest my case. |

AFONJACOW:steam engine runs on water nah |

takenadoh: It is you that did not get it. Will putting a 50kg bag of cement in the boot of a G63 AMG make it slower than a G500? As an extra, there is a principle called power to weight ratio when designing cars. The only reason weight shedding is done on cars is to get more power output to carry a lesser weight |

muller101:but its not popular ? |
Re: Mazda's Breakthrough Makes Sparkless Petrol Engine As Efficient As Diesel Engine by muller101(m): 10:49am On Sep 07, 2017 |
AFONJACOW:yeah . Check my profile DP that's a steam engine I run that with hot water. |

muller101:hahahahahahahaha you are funny ... |
Re: Mazda's Breakthrough Makes Sparkless Petrol Engine As Efficient As Diesel Engine by muller101(m): 11:00am On Sep 07, 2017 |
AFONJACOW:I am no joking bro. That's a 20 horse power steam engine. If u know the principles of how locomotives Operates u will know I am serious |

Let's hope it's efficient with the discharge of heavy work load considering the air/fuel ratio |

AFONJACOW:there are cars that burn hydrogen ad oxygen to release steam. Thats close enuf to water abi? |

Denn: If you know how diesel engine runs then you wouldn't be able to draw up conclusions. They have clearly made a statement of Making two technologies as I have earlier pointed out. Who knows if they know the homogeneous tech is a failed one already. I might be wrong though until we the engineers visually see and feel this on our dirty hands |

Nice job |
Re: Mazda's Breakthrough Makes Sparkless Petrol Engine As Efficient As Diesel Engine by mayor2013: 11:42am On Sep 07, 2017 |
These manufacturers are getting tired daily. Getting tired of fines been imposed by environmental protection agencies. Fines running into billion of dollars. That's why they keep coming up with different means of dummy technologies of cutting emission strict laws. Germany on this are even more strict. I hope they get this right |

takenadoh:I think you don't get it. Since it's petrol, you don't need such high pressures as in diesels, if you understand PV=nRT. The spark plug ignites it, but given that it has a low flash point, it doesn't need to reach auto-ignition temperature using extremely high pressures, unlike diesel which must exceed auto-ignition temperature since it can't ignite by spark. So, as Denn said, the engine may not be significantly heavier. |

mayor2013: I seem not to understand your point sir |
Re: Mazda's Breakthrough Makes Sparkless Petrol Engine As Efficient As Diesel Engine by DaimlerBen(m): 4:44pm On Sep 07, 2017 |
mayor2013:It hasn't failed. This is the beginning of true flex fuel cars, running on everything from kerosene to vegetable oil. 1 Like |
