Perhaps surprisingly, the greenhouse gas footprint of blue hydrogen is more than 20% greater than burning natural gas or coal for heat and some 60% greater than burning diesel oil for heat, again with our default assumptions. Our analysis assumes that captured carbon dioxide can be stored indefinitely, an optimistic and unproven assumption.
GE Transportation announced the first sale of its new 12V250 Marine Diesel Engine that is designed to meet EPA Tier 4i and IMO Tier III Emissions standards. SCR requires the use of a dieselexhaust fluid, typically urea, to reduce NO x in an after-treatment of exhaust gas.
Researchers from the College of Engineering at Anna University (India) are proposing the use of acetylene as a dual fuel with diesel in compression ignition engines. In order to decrease the NO x emissions from acetylene–diesel engine, cooled EGR was employed. C 8 –C 20. Density kg/m 3. Lower heating value of stoich. mix (kJ/kg).

The Audi R18 e-tron quattro diesel hybrids ( earlier post ) that will race at Le Mans this coming weekend (14-15 June) are the lightest and most fuel efficient LMP1 racers has yet to bring to the track. For the powertrain, Audi, in the 25 th year of the TDI engine, has developed a new diesel 4.0-liter liter V6 unit for Le Mans.
The EPFL system captures CO 2 directly in the trucks’ exhaust system and liquefies it in a box on the vehicle’s roof. First, the vehicle’s flue gases in the exhaust pipe are cooled down and the water is separated from the gases. Researchers at EPFL have patented a new concept that could cut trucks’ CO 2 emissions by almost 90%.
Results of testing on a Euro 6 BMW 320d diesel by the German environmental organization Deutsche Umwelthilfe (DUH), ZDF’s WISO and a software expert point to the use of inadmissible defeat devices, according to DUH. The vehicle must have fully functional exhaust gas cleaning in all normal operating situations.
Global automotive supplier DENSO Corporation has developed a new 2500-bar diesel common rail (DCR) fuel injection system; DENSO says this is the currently the world’s highest injection pressure for a diesel common rail fuel injection systems comprising injector, fuel pump and common rail.

Or it relates to fuels such as hydrogen, that would not at all emit CO 2 at the exhaust pipe. Since many chemical processes, like creating hydrogen, require electricity, it is crucial that the latter is produced, transmitted, and stored in an ecological friendly way, i.e. by renewable means. but also second-generation biofuels).
These include a smart alternator that recovers energy while coasting and stores it in the battery; engine cooling circuit optimization that reduces the warm-up time; and a variable displacement oil pump that adjusts the oil pressure in the most appropriate way, reducing the power consumed by the pump.

On the Glider, the heat of the exhaust gases is converted into electrical energy by a thermodynamic system that works like a compact, efficient steam engine based on the Rankine cycle. All Iveco diesels and hybrids at the event are fueled with NExBTL renewable diesel (hydrotreated vegetable oil) from Neste Oil.
The K6 engine uses six strokes instead of four to reduce the pressure of exhaust gases, which allows it to harvest more energy rather than expelling it with the gas. Shedd said the engine could be up to about 30% more efficient than a standard diesel engine, depending on the engine load and speed. —Timothy Shedd.
At the 38 th International Vienna Motor Symposium this week, Continental is showcasing a 48-volt hybrid diesel vehicle which meets very stringent RDE (real driving emissions) limits on CO 2 and NO x. The first 48-volt diesel hybrid has already gone into production in Europe, and a second production launch is already in the pipeline for 2017.
Volvo’s hybrid buses have a downsized diesel engine and an electric motor that can operate the bus independently or jointly. When the bus brakes, the brake energy is utilized and stored in a battery, which then drives the electric engine when the bus accelerates again. This gives a quiet and exhaust-free environment at bus stops.

The Scuderi split-cycle design divides the four strokes of the conventional combustion cycle over two paired cylinders: one intake/compression cylinder and one power/exhaust cylinder, connected by a crossover port. The Scuderi engine can run off of multiple fuels such as natural gas, liquid propane, diesel or bio-fuels. Earlier post.)
Diesel engine vehicles can be damaged by using low quality dieselexhaust fluid (DEF). Repairs can be very expensive with long downtime possible, and damage could void the manufacturer’s warranty.
This fluid is stored until the driver next accelerates the vehicle which reduces fuel consumption and wear on the engine. In “fuel economy mode,” savings occur when stored energy is used to launch the vehicle without power from the primary engine; testing in this mode has shown more than a 50% reduction in brake wear.

A team from the International Council on Clean Transportation (ICCT) with colleagues from the US, China and Germany tested 73 Euro 6 diesel passenger cars on a chassis dynamometer over both the European type-approval cycle (NEDC, cold engine start) and the more realistic Worldwide harmonized light-duty test cycle (WLTC version 2.0,
Natural gas is stored in its liquid state at -130 °C and at 9-bar pressure, which is then converted into a gaseous state before being injected into the engine. Exhaust gas is treated by a standard passive three-way catalyst that does not require the use of any additives.
The market will receive a boost from new diesel locomotive emissions regulations scheduled to go into effect in the European Union in 2014 and in North America in 2015, which will require diesel locomotives to receive substantial changes or exhaust treatments. during the same period, with annual unit sales exceeding 170.
DME offers diesel-quality performance with a high cetane number and low auto-ignition temperature, but burns cleanly without producing any soot. It is an excellent compression ignition fuel which, like diesel, requires no separate ignition mechanism. It can safely be stored on-site for extended periods of time. DME and diesel.
The remaining two-thirds are lost as waste heat going into the environment through the car’s exhaust emissions and through the radiator. A great deal of thermal energy is generated while driving and is available after coming to a stop—energy stored in components such as the engine and transmission.
Amminex has developed an Ammonia Storage and Delivery System (ASDS) which has demonstrated its efficiency to almost completely eliminate nitrogen oxide (NO x ) pollutants from diesel engines. Conventional dosing technology is based on spraying an aqueous urea solution (dieselexhaust fluid, DEF) into the exhaust stream.
It was developed in collaboration with CRF [Centro Ricerche Fiat], a process that has involved equipping the new machine with all of the features required to ensure it will deliver the kind of performance associated with a conventional diesel tractor, both in the field and on the road. —Riccardo Morselli, Innovation Product Development.
