Effectivement.

Faudrait déjà m'expliquer comment faire fonctionner un moteur diesel, en d'autres termes fonctionnant en mélange pauvre et allumage par compression, avec un carburant qui ne se consumme correctement que pour une stéchiométrie bien définie et qui demande un allumage commandé

Rhalala...

... M'enfin je préfère miser sur les moteurs à compression variable dont on parle je ne sais plus trop où

This type of system is suitable for mechanically-injected diesel engines.

Conversion of a diesel engine is different from that of a petrol engine. Diesel is always burned - you just have the option of adding LPG or not. Adding LPG helps the diesel to burn more completely. This tends to clean up emmissions and increases the power output - allowing the use of a lighter throttle and leading to fuel economy.
Care must be taken to avoid feeding in too much LPG as ADDING TOO MUCH LPG MAY DAMAGE THE ENGINE. Tinley Tech cannot be held responsible for damage caused by incorrect tuning.

The benefits of the system are most evident on mechanically injected engines. In all cases, the savings in running costs will depend on the tuning of the LPG system and the way the vehicle is driven.

Diesel LPG Conversions

Diesel engines can be converted to run partly on LPG, partly on diesel. This method uses the combustion of the diesel to ignite the LPG. The benefits include large increases in power and reduction in emissions, particularly the black smoke often associated with diesels.
Typically a ratio of 30% LPG to 70% diesel is possible. No adjustments are required to the diesel injection system and fuel savings come from the fact that throttle openings are lower due to the greatly increased power, which basically means you do not have to press the accelerator as hard to get the same performance.
Fuel savings up to 30% are possible with the increased power levels seen as a major benefit to users.

Converting a diesel engine to use LPG is different from a petrol engine conversion. Since the diesel engine has no spark plugs, the only way the LPG can burn is if diesel is used to ignite it. So diesel is always used. The addition of LPG gives a more complete burn of the diesel and can result in a reduction in the amount of black smoke emitted from the exhaust. More significantly, it increases the power from the engine. The way the extra power is used has a direct influence on the fuel economy.

If you drive at the same pace as you do when running on diesel alone, the addition of LPG will allow you to use a smaller throttle opening. This means that the load on the engine is the same, but the amount of diesel used will be less. Many of our customers report savings of 20 to 30% in fuel bills. The older, mechanical injection engines tend to give greater savings than the newer, more efficient, electronic injection engines.

If you decide to use the extra power, the load on the engine will be higher and, at large throttle openings, the engine will burn the normal amount of diesel in addition to the LPG. Thus, your fuel bill may well be higher than when using diesel alone.

Given the above, it is difficult to predict how the use of LPG will affect fuel bills in the context of the diesel engine.

The Tinley Tech diesel LPG conversion kit is intended for use by owner-drivers rather than commercial users, where drivers tend to drive hard.

Ah oui! Le MCE5 de PSA (ou Renault? ).
Là, c'est à mon tour de dire "mouais ...". Je préfère pas de thermique du tout, moi ... ou le moins possible

Pour diminuer la pollution des camions diesel, les modèles récents conforment à une norme euro-qqch sont munis d'un additif "adblue" ; vous savez en quoi ça consiste ?
Aux USA et au Canada ce dispositif équipe aussi les (rares) voitures diesel en vente comme la Chevrolet Captiva (et les WW-Audi mazout en vente là bas).

Déjà qu'avec les moteurs diesel, on est souvent dans la m....., si en plus il se met à puer la pisse, c'est la totale

Le dépistage du cancer colorectal fera t il partie des prochaines opérations du contrôle technique ?

pour les commentaires à tendance scatologique, les moteurs à gaz issue de la macération des excréments marchent très bien.
Grosse expérience en Angleterre sur le sujet
Idem en chine
