Water injection for less nitrogen oxides

CITY, COUNTRY OR RIVER: MAKING DIESEL READY FOR THE FUTURE

 

Towards a Clean Environment - Reducing Exhaust Emissions from Diesel Engines With an Innovative Technology

THIS IS GODIESEL

Time for water - against diesel exhaust gases! GoDiesel, founded in 2017, has developed a process that halves nitrogen oxide emissions. Without any loss of performance, consumption or CO2 emissions. A technology that can be retrofitted to practically all diesel engines in passenger cars and inland waterway vessels. Water injection reduces the very high combustion temperatures and thus combats the cause of the problematic NOx emissions. The effectiveness of our process has been scientifically proven. The greatest advantage over the systems available so far lies in the universally applicable, extremely space-saving design, the simple technical controllability, the high availability and the favourable price. GoDiesel has combined a fundamentally proven process with modern know-how and intelligent electronics. Beneficiaries are both humankind and the environment.

Retrofitting of Diesel Automobiles

Treat NOx with water

In water injection, distilled water is injected into the intake air of the engine. We are thus tackling the core problem of the diesel engine: The very high combustion temperatures which cause the NOx emissions. GoDiesel lowers the temperature peaks. To a level that continues to guarantee the function of diesel particle filters or storage resp. oxidation catalytic converters. GoDiesel water injection can be retrofitted to all diesel passenger car engines of the Euro 4, Euro 5 and Euro 6 b/c emission classes without exception. As various research projects have shown, the efficiency of the diesel engines remains fully intact: No increase in fuel consumption or CO2 emissions - running smoothness and performance remain unchanged. In the Automotive Sector, GoDiesel water injection has a USP: It is the only available technology that combats exhaust pollutants right from the start instead of treating them in the exhaust tract. Provided a Retrofit Regulation is issued by the Federal Government, the GoDiesel system will be available within a few months and can be used on a wide basis thanks to its favourable price. Guarantee insurance included.

Water Injection for Waterways Transport

Always a hand's width of water in the intake air

The high nitrogen oxide pollution in the cities has also led to a focus on the reduction of exhaust emissions from ship engines. GoDiesel offers river transport a new and very economical way of reducing nitrogen oxide emissions. Water injection makes sense even for the predominantly smaller engines used in passenger shipping. Particularly because the system requires extremely small installation space as well as very little maintenance and does not increase operating costs. Additional benefit for Ship Operators: With the Onboard Electronic Control System, GoDiesel has not only a NOx sensor but also an integrated fuel consumption sensor. The combination of water injection with new fuels offers further potential for Inland Navigation. A GoDiesel research project using GTL fuel is currently being carried out at HTW Saar University. The aim is to simultaneously reduce nitrogen oxides and fine particles by 50 percent and to completely avoid diesel odours.

Diesel Engine Exhaust Gases and Retrofitting - Abbreviations

NOx, SCR, WLTP and Co. - what do they mean?

NOx

Nitrogen oxide is a collective term for various gaseous compounds consisting of the atoms nitrogen (N) and oxygen (O). Put simply, only the two most important compounds NO (nitrogen monoxide) and NO2 (nitrogen dioxide) are considered. Nitrogen oxides are among the "mass pollutants" in the air: more than one million tons are released each year only in Germany. In Germany, the common classification as an extremely harmful irritant gas is not undisputed.

SCR / AdBlue

The SCR technology (Selective Catalytic Reduction) consists of a catalyst into which a mixture of 67.5 percent water and 32.5 percent synthetic urea (brand name AdBlue) from a separate tank is injected. In the exhaust system, the liquid then reacts with the nitrogen oxides of the engine combustion within fractions of a second and converts these emissions into water vapor and nitrogen. SCR technology requires an extremely high level of engine control adaptation.

EGR

The abbreviation stands for Exhaust Gas Recirculation to reduce NOx emissions within the engine. Part of the exhaust gas is cooled and mixed back into the charge air. This reduces the peak temperature of the combustion. However, EGR can only be used to a very limited extent, as excessive admixture leads to negative effects such as loss of performance and an increase in particulate emissions. The resulting sooting of the EGR valves triggered the VW Diesel Scandal.

WLTP (WLTC)

Since September 1, 2017, the new "Worldwide Harmonized Light-Duty Vehicles Test Procedure (Cycle)" has applied throughout the EU to the registration of new passenger cars, following the NEDC (New European Driving Cycle) which has been in force since 1992. The new test does not only take longer, namely 30 instead of 20 minutes, but the tested vehicles also accelerate significantly more frequently, up to a recommended motorway speed of 130 km/h. The gearshift points are also readjusted during acceleration. In addition, the proportion of time during which the vehicle is at standstill is reduced.

RDE

The RDE test procedure (Real Driving Emissions) provides more information about the real emission behaviour during operation on the road and has been valid in the EU since September 2017. Under laboratory conditions, approx. 25 % lower emissions compared to RDE are measured. This means that test detection by the vehicle is no longer possible (VW Diesel Scandal). The vehicle is driven outside on a stretch of road and accelerated and braked there. A portable emission measurement system (PEMS) is used to determine the particle number and the concentration of nitrogen oxides.

NOx Limits

The diesel debate centres on Euro 4, 5 and 6 b/c vehicles. The table shows the valid target/actual values according to RDE:

Euro 4

> Legal specification NOx limit value 250 mg

> Permissible NOx limit value Factor 2.1 RDE* 525 mg

> Practised value RDE (source: UBA, ADAC) 674 m

Euro 5

> Legal specification NOx limit value 180 mg

> Permissible NOx limit value Factor 2.1 RDE* 378 mg

> Practised value RDE (source: UBA, ADAC) 906 mg


Euro 6

> Legal specification NOx limit value 80 mg

> Permissible NOx limit value Factor 2.1 RDE* 168 mg

> Practised value RDE (source: UBA, ADAC) 507 mg

*valid until 2020

THE TEAM BEHIND GODIESEL

Can a startup also be founded by "old stagers"? Yes, it can! We share a strong passion for cars and ships as well as the joy of sustainable technologies for a clean environment. For GoDiesel, this has become a commitment to the diesel engine. Technologies such as water injection point as much to the future as the combination with new, alternative fuels. Because diesel will be used for a long time to come, whether on the road or on the water. And for climate protection. We are convinced of this.
