Volvo has taken out a patent for a new technology that significantly cuts the harmful substances emitted by diesel engines. Perhaps the fuel's salvation.
Volvo will extend the life of the diesel engine with a new patent for a technology that significantly reduces the emission of harmful substances.
In order to comply with the current emission requirements, manufacturers of diesel engines today often use urea. Urea reduces the emission of nitrogen oxides, but Volvo Trucks has now, according to Carmoses , developed a new method that optimizes the use of urea and further reduces emissions.
Volvo's patent application describes a technology that provides more precise control over the urea agent. This is achieved by modifying the opening of the urea injectors.
By using a specific material whose composition Volvo keeps secret, the injectors can regulate the amount of urea with greater precision.
The material reacts to the temperature in the exhaust gases and adjusts the injector opening – and thus the amount of urea – accordingly. In addition, a heater placed on the material can allow for manual control of the urea consumption.

With this technology, Volvo Trucks can control emissions more effectively than with existing systems. This could prove decisive for the future of the diesel engine, as the emission requirements are constantly being tightened.
Patents are nothing new in the automotive world. Audi, for example, has developed a technique so that electric cars can drive in water. And Ferrari? Yes, the Italians have actually patented an idea to turn a V6 engine upside down and fill it with hydrogen. Read more about it here .
