Optical study of flow and combustion in an HCCI engine with negative valve overlap [PDF]

, 2006
One of the most widely used methods to enable Homogeneous Charge Compression Ignition (HCCI) combustion is using negative valve overlapping to trap a sufficient quantity of hot residual gas. The characteristics of air motion with specially designed valve

Possible applications of prechambers in hydrogen internal combustion engines

Combustion Engines, 2022
The use of hydrogen as a fuel for an internal combustion engines has caused many problems for years, the most significant of which seems to be the excessive emission of nitrogen oxides and the tendency to knock combustion.

Alignment of Smulation Methodology and Measurement Techniqus to Predict the HC-Distribution at Catalyst Inlet for Exhaust Fuel Injection

International Journal of Automotive Engineering, 2019
Injection of fuel into the exhaust system is used to support the operation of exhaust gas aftertreatment systems. When injecting a fluid into the exhaust system, one major challenge is to design the exhaust system for optimal fuel distribution and to ...

Concepts for Hydrogen Internal Combustion Engines and Their Implications on the Exhaust Gas Aftertreatment System

Energies, 2021
Hydrogen as carbon-free fuel is a very promising candidate for climate-neutral internal combustion engine operation. In comparison to other renewable fuels, hydrogen does obviously not produce CO2 emissions.

Development of a Novel Gasoline Particulate Filter Loading Method Using a Burner Bench

Energies, 2021
In view of the deliberations on new Euro 7 emission standards to be introduced by 2025, original equipment manufacturers (OEMs) are already hard at work to further minimise the pollutant emissions of their vehicles. A particular challenge in this context
