wheelnut,
too many bombshells hitting lately for me.

firstly the toyota Safe T Cell is a scam,

and now there is only 2 toyota guys, but they make out there is several by using different names???
i need to lie down…….

Dingo; Go Toyota; Oh What A Feeling; Go Prius; Australia’s First Taste of A Tough Truck; Tomas79; TP are going to hate reading that opening sentence…

“BMW has wiped the floor with its competitors in the latest engine awards. With the German marque claiming honours for no less than 5 engines”

that is of course; if they decide to read it or simply choose to ignore it as usual

PS – I know it sounds like a lot of people but its actually juust 3

Hey No Name if you check the results BMW only lost by 3 points to Toyota with their engine,they will get them next year!

Andrew……..babe you know I’m “flawless”

is this one still going???

you spelt “Floor” wrong by the way BM

Right there missile. The problem with the crappy Prius getting the award is its the whole car not just the engine.
BMW’s diesels I would suggest are the market leaders for outright performance now, even ahead of the Frogs efforts.

It works as I have one on my BF Falcon LPG ute…..get around 700kms to a tank!

Andrew M, you will notice that the energy figure you quoted is energy per unit mass not energy per unit volume like I have been quoting, Furthermore, as your reference indicates, LPG is less dense then petrol (which is rather obvious) hence validating what I have been saying.

“a cold air kit alters the efficiency of the motor does it not” – at full throttle yes it does. However by definition a throttle is a variable restriction. When you close the throttle you are restricting the pumping efficiency of the engine and hence you cold air intake is not going to help a lot. However with the throttle fully open its provides the least restriction, and as a result other restrictions that occur before it become very important hence we get people fitting cold air intakes.

“fuel still gets fed into the motor at the same rate whether or not the oxygen is there to efficiently burn it.” This statement is incorrect. The fuel air ratio remains nominally constant and is governed by the inlet manifold pressure on engines with a carburettor or electronically on fuel injected engines.

“more oxygen or other beneficial gases into the air box to me sounds logical that there would be less wasted fuel.” Firstly you can “waste” less fuel simply by leaning the mixture. Your engine won’t last very long but feel free to give it a go. Secondly how much of these beneficial gases do you think this joe cell is producing. Electrolysis of water is nothing new and well understood. However the way that is set up and used in this application guarantees that the rate of gas production will insufficient to make one iota of difference.

“sorry but im not going to be one who instantly writes the concept off.
it does hold some merit” That’s your choice and you are most welcome to do that. However the concept has been around for years and has been shown not to work.

Titan,
QUOTE……….
LPG provides about 8% more energy per unit weight (LHV = 19,757 BTU/lbm) than gasoline. Theoretically, vehicle operation with LPG should be more efficient than with gasoline, i.e., the vehicle should attain better specific fuel consumption and improved mileage. However, this will only happen if the engine design is optimized for LPG fuel. If a gasoline engine is converted to operate on LPG this increased efficiency will not be realized due to the lower density of LPG compared to gasoline and also its slightly higher oxygen demand (LPG stoichiometric A/F = 15.8). The lighter density fuel displaces air in the intake manifold, and thus, less air per cycle is induced to the cylinders. This translates to a decreased volumetric efficiency and a loss of power compared to the original gasoline rating of the engine.

also with HHO,
the reaction is claimed from the gases being taken through the airbox.
a cold air kit alters the efficiency of the motor does it not?
the oxygen entering the motor affects the burning efficiency.
blank off half of the air inlet and you will notice it for the worse.
put a bigger air funnel on and you will notice it for the better.
more oxygen = better economy and power.
the fuel still gets fed into the motor at the same rate whether or not the oxygen is there to efficiently burn it.

more oxygen or other beneficial gases into the air box to me sounds logical that there would be less wasted fuel.

sorry but im not going to be one who instantly writes the concept off.
it does hold some merit
