FAQ - Conversion service

How much does conversion cost?

All prices for our conversion sets can be found in our Online Shop. A few inexpensive parts might have to be purchased, too.

Does the conversion come with a warranty?

All parts included in the conversion set will be under warranty of which conditions are described on the ELSBETT website. Installation, if done by an ELSBETT service partner, has a one year limited warranty for commercial customers and two years for private customers.

Do automobile manufacturers support and/or give clearance for conversion?

No. Currently there aren’t any quality standards for PPO conversions. Therefore, no “third party” modifications can be certified. If you own a vehicle which is still under warranty, conversion may undermine validity of this warranty. If necessary the manufacturer will have to decide in each individual case if warranty will be granted or denied.

Does conversion change the vehicle performance?

Performance and fuel consumption of the engine running on diesel or pure plant oil (PPO) will be practically the same.

Does conversion change emissions?

When running on PPO your emissions won’t contain SOx and will have less CO2 than when running on diesel. The CO2 output is equal to the CO2 extracted from the environment by the plants that are the source of the oil you will use.

What is ELSBETT’s history in conversion technology?

ELSBETT did their first conversion of a “pre-chamber” diesel engine in 1980 (VW Golf).

The first heavy truck engine was done in 1988. Conversions and converters for stock diesel engines have been available since 1989. Since 1997 single tank systems have been available for “pre-chamber” and (1999) “direct-injection” diesel engines. Conversion of “common rail” engines has been done since 2002. Also since 2002 ELSBETT offers conversions for most European made heavy trucks (installed or as a conversion set).

In addition to this ELSBETT has done many other kinds of conversions, from agricultural to rail equipment.

Why should I choose an ELSBETT conversion?

ELSBETT has more than 30 years of experience in SVO technology and a large fleet of test vehicles. They offer a wide range of vehicle specific conversions, single-tank or two-tank. Their knowledge and expertise will guarantee the best conversion solution for any vehicle.

ELSBETT DIY sets are the same as the conversions done in the ELSBETT shop. Feedback from customers helps with the ongoing development and improvement of the conversions.

ELSBETT is in the first place a research and development company. The conversion sets have been designed so that qualified mechanics can perform installation independently, anywhere. Therefore, ELSBETT is constantly expanding their network of service partners not only nationally but worldwide.

ELSBETT can be seen as pioneer of the PPO engine, has brought the PPO-conversion movement to life and wishes to continue to be the driving force behind it.

What is the relation between the “ELSBETT Engine” and ELSBETT conversion technology?

The ELSBETT Engine was developed in the 70’s as technological development tool for the automobile industry. Direct injection, turbo charging, intercooling, unit injection and many other technical details that can be found in modern diesel engines were developed at the time. It facilitated the breakthrough of the direct injection (TDI) for passenger cars. The ELSBETT Engine could run on diesel as well as on PPO.

At the time the industry showed little interest which lead ELSBETT to invest in small scale production of engines for “engine swap conversions” of Mercedes and VW vehicles that turned out to be very costly. This product was advanced and pretentious but too expensive for most people interested in it. Production was stopped because of slow and irregular sales.

ELSBETT kept high standards for energy efficiency and performance. For the use of vegetable oil as fuel the ELSBETT Engine has been an invaluable pool of experience.

Is the ELSBETT Engine still in production?

No. The production stopped in the mid 90s due to the reasons described above. But many of these engines are still worldwide in service today.
