Economical operation on LPG is an increasingly desirable alternative today, but modern direct injection engines do not support it very much. Nevertheless, we found a modern and above all reliable solution.

Gasoline and diesel prices, attacking ever higher and higher values, lead many of us to think whether we should really give the gas drive a chance and not take advantage of its low taxation, leading in the end to an acceptable price. And even if the possible rebuilding also costs something, with today’s price difference the initial costs of its acquisition will be recouped relatively quickly. And then you just save. But modern direct injection engines are not completely compatible with LPG. There would still be one solution here.
Direct injection is not an ideal choice for LPG
Let’s first quickly outline why gasoline direct injection engines are not very suitable for converting to LPG. The fuel injectors are in the combustion chamber exposed to high temperatures, during operation their cooling is provided by injected gasoline. That is why LPG systems often maintain simultaneous petrol injection even when running on LPG, the economy of operation is understandably not as advantageous as when running purely on gas.

However, the economic side of the matter is not the only complication of the joint “coexistence” of gas and direct gasoline injection, on the contrary, there are significantly more technical ones. Designers and manufacturers of contemporary however, modern engines prefer direct gasoline injection for many reasons, thus finding a “compatible” engine for problem-free conversion to LPG is increasingly difficult. However, we should have one solution, and it is, paradoxically, from one of the best engine manufacturers in the world – the Japanese Toyota.
Japanese engines with the best pedigree
This is because the 1.8 Valvematic engine retained indirect gasoline injection, and companies involved in the conversion of engines to LPG absolutely love this unit. You can find it, among other things, in your favorite Avensis up to the year of production 2018, where it has a power of 147 hp, as in the first and second generation Auris. A cheaper version of the 1.6 Valvematic is also available in both models, but if you can choose, go for the more powerful version, as fuel consumption is almost the same for both versions.

Both models will then offer you the best of the “Toyota of the world”, from reliability to specific superstructure neutrality and inconspicuousness. And if you can rise above a certain Japanese ethos that is u of Toyota cars is still present (unlike, for example, Mazda or Nissan, which builds already completely European-looking cars), you will get a great partner for life. And when converting to LPG, great economy of operation. One of our LPG favorites? I wouldn’t see it any other way.
