Their work involves the use of Mahle’s prechamber jet ignition system (MJI). Engine tests have shown that by using this technology, the mixture of hydrogen and air can be ignited and burned at a high compression ratio, which makes the combustion process very efficient and stable. This paves the way for hydrogen generated in climate-neutral processes to be used in heavy-duty and off-road applications, such as excavators, track vehicles, and wheeled loaders.

“The use of hydrogen as a combustion fuel has the potential to make many heavy-duty and off-road applications climate-neutral quickly” said Peter Wieske, Director Corporate Advanced Engineering at Mahle. “A large number of studies in recent decades have shown that hydrogen can be used in internal combustion engines without any problems.”

Bouzid Seba, Head of Predevelopment at Liebherr Machines Bulle, added that the expertise of Liebherr’s engineering teams in off-highway engine combustion and research on alternative fuels has been critical in this project.

In order to achieve stable operation with a high compression ratio whilst avoiding engine knock and pre-ignition, hydrogen engines must be operated with a large amount of excess air. The energy from a conventional spark plug is not enough to ignite such a mixture. Mahle Jet Ignition solves the problem by burning a small amount of an ignitable mixture in a prechamber cylinder. The resulting gas plasma is passed through small openings into the main combustion chamber and, due to its high energy content, rapidly and evenly ignites the main gas mixture. Tests with H966 and H964 engines from Liebherr have delivered excellent results in terms of combustion speed, performance, and emissions.

Hydrogen engines are ideal for high load cycles with sudden load changes and cope well with heat, dust, and vibrations. This makes them an excellent choice for use in heavy-duty and off-road applications, where fuel cells hit their limits more quickly.

GET YOUR EX LOVER BACK.VIA: dromokpo@gmail.com This is my testimony of life that I will tell everyone. I have been married for 25 years Another woman had a spell to get me away from my lover, My husband left me and the children and we suffered for 2 years until I saw post about where this man Dr Omokpo has helped so many people recover their broken marriages and relationships to get their ex lovers back. I decided to send him a message about my broken marriage and family about how my husband left me and for him to help me bring back my loving husband home. This great man told me what to do and I followed him as he instructed. After 48 hours, as he told me, I saw a car enter the compound. I was shocked when I saw my husband.

Hi everyone... Am so excited to share my testimony of a real spell caster who brought my husband back to me. My husband and I have been married for about 6 years now. We were happily married with two kids, a boy and a girl. 3 months ago, I started to notice some strange behavior from him and a few weeks later I found out that my husband is seeing someone else. He started coming home late from work, he hardly cared about me or the kids anymore, Sometimes he goes out and doesn\'t even come back home for about 2-3 days. I did all I could to rectify this problem but all to no avail. I became very worried and needed help. As I was browsing through the Internet one day, I came across a website that suggested that Dr. Wale can help solve marital problems, restore broken relationships and so on. So, I felt I should give him a try. I contacted him and told him my problems and he told me what to do and I did it and he did a spell for me. 48 hours later, my husband came to me and apologized for the wrongs he did and promised never to do it again. Ever since then, everything has returned back to normal. My family is living together happily again.. All thanks to Dr. Wale If you have any problem contact him and I guarantee you that he will help you. He will not disappoint you. you can WhatsApp him +1(978) 406-9575 or Email him at : everlastingspellcast@gmail.com or view his website for more review https://everlastingspellcaster.website2.me/contact
