Common rail direct fuel injection is a direct fuel injection system for petrol and diesel engines.

On diesel engines, it features a high-pressure (over 1,000 bar or 100 MPa or 15,000 psi) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles). Third-generation common rail diesels now feature piezoelectric injectors for increased precision, with fuel pressures up to 3,000 bar (300 MPa; 44,000 psi).

In petrol engines, it is used in Gasoline direct ....etc

COMMON RAIL DIRECT INJECTION (CRDi) AS A POWER GENERATING UNIT IN AUTOMOTIVE SYSTEM


INTRODUCTION
While the Japanese are leading in petrol direct injection technology, Germany's Bosch, working in conjunction with several European car makers, Have pioneered Common-Rail Direct Injection for diesel engines. Compared with petrol, diesel is the lower quality ingredient of petroleum family. Diesel particles are larger and heavier than petrol, thus more difficult to pulverize. Imperfect ....etc

ABSTRACT
Compared with petrol, diesel is the lower quality product of petroleum family. Diesel particles are larger and heavier than petrol, thus more difficult to pulverize. Imperfect pulverization leads to more unburnt particles, hence more pollutant, lower fuel efficiency
and less power.
Common-rail technology is intended to improve the pulverization process. Conventional direct injection diesel engines must repeatedly generate fuel pressure for each injection. But in the CRDI engines the pressure i ....etc

Abstract

Currently, commercial gasoline direct injection engines mainly use wall-guided combustion system to prepare stratified mixture. In this system, the fuel droplets injected from one cylinder side usually tend to wall wet on the piston crown and the other side of the cylinder, which causing an increases of the HC emission. The liquid phase LPG has a lower boiling point and a higher vapor pressure than gasoline. When it is injected with the pressure more than 5MPa, flashing will occur, which speed ....etc

Twin Spark Ignition
Normal ignition system has a single spark plug. The flame front created by the spark takes some time to reach the entire combustion chamber. Hence the burning of air-fuel mixture is slow and incomplete.

In case of twin spark, two spark-plugs fire at the same time. This simultaneous firing and swirl of the air-fuel mixture results in complete combustion. This action is digitally controlled by the DTS-i system (namely the twin spark plugs, TRICS II and intelligent CDI)

Abstract
The development of four-stroke, spark-ignition engines that are designed to inject gasoline directly into the combustion
chamber is an important worldwide initiative of the automotive industry. The thermodynamic potential of such engines for
significantly enhanced fuel economy, transient response and cold-start hydrocarbon emission levels has led to a large number of
research and development projects that have the goal of understanding, developing and optimizing gasoline direct-injection
(GDI) combustion systems. The proces ....etc

ABSTRACT
A high-frequency electrical resonance-based ignition concept
is in development to replace conventional spark ignition
functionality for gasoline engines employing various types of
fuel injection methods. The concept provides the benefit of a
continuous discharge phase and the electrical power of the
discharge can also be adjusted to the needs of the combustion
conditions.
This concept employs an alternative method of generating
high voltages, using inductors and capacitors trimmed such
that the supplied energy steadily ....etc
