CLASSIFICATION OF THE DIESEL ENGINES
http://perso.wanadoo.fr/jean-pierre.rossi/diesel/diesel.htm
|
1) Indirect Fuel injection engines |
The vehicles diesel with or without turbo equipped with preheating plugs on which one has obligation to make preheat before starting are engines said to indirect injection because the injector does not inject directly into the cylinder but into a precombustion chamber.
They are equipped with a pump rotary injection H P manual
(or a little electronics) which distributes the fuel successively to each
cylinder by opening the injectors the ones after the others by the pressure of
the gas oil.
Puncture-proof advantage
Disadvantages : Ca rows in the coasts except the
turbos and that smokes in the transient states with acceleration.
Their pressure of injection is approximately
130 bar

2) Direct Fuel injection engines |
TDI in group VW, the "old engines" 90 and 110 CV of
the golf and Passat for example, dti at Renault, and the tddi (or the transit)
at Ford, the IVECO and FIAT TDI equipped with engines SOFIM are diesel engines
with direct injection (direct English injection).
Favour : puncture-proof and lower consumption,
highly reliable, less ruptures of the cylinder head gaskets on Sofim (Iveco
Master and FIAT Ducato)
( All the engines of Trucks, the tractors farm, the
machines of public works are of this type) (Until new order)
Disadvantages they are "rather noisy" one
recognizes them with their particular slapping related to the pressure of higher
injection and they would have had evil to meet the conditions of the future
anti-pollution laws (especially models without turbo).
They are equipped with a pump rotary injection HP manual (with electronic elements and sometimes even a calculator). The injection pump distributes the fuel successively to each cylinder by opening the injectors the ones after the others by the pressure of the gas oil but the injector injects directly into the cylinder. These engines (in general) are not equipped with preheating plugs, it is not necessary to preheat the engine to start. *
* They are on the other hand often team of Thermostart located in the pipe of
exhaust to heat the air intake (with starting)
Their pressure of injection lies between
180 and 250 bar

3) Moteurs Common rail and Injecteur Pumps |
The JTD of group FIAT, HDI of group PSA, dci Renault, TDCI Mercedes, D4D Toyota
are as for
them of the engines known as Common rail.
I.e. that they are equipped with a rotary pump which supplies a common tube
(common rail) and the injectors are supplied by this tube, the opening of each
injector is done by an electromagnetic sluice gate (source of breakdown) and a
calculator to give the order to the injectors to open).
It is a technique FIAT which was transferred at Bosch. (In the future, the
electromagnetic sluice gates should be replaced by piezoelectric systems)
There are an alternative which appears on the smaller engines (diesels Renault
and common PSA Ford) developed by ex Lucas and now Delphi which replaces the
tube by a sphere but operation is the same one.
The supply pressures are included/understood between 1300 and more than 2000 bar
It is not finished group WW complicates with their new TDI formulates: the 100
and 130 CV of the Golfs and Passat which them are equipped with a system says
injecting pumps i.e. which there are no more rotary pump but on the other hand
the pump are integrated in the injector. When there is the whole is changed (on
a cylinder).
With regard to the LT they would seem to be equipped with Common rail dixit DC
magazine
The formula of the injectors pumps seems a little more reliable but according to
the specialists will have can be more evil to follow the future anti-pollution
standards.
Their pressure of injection: more than 2000 bar
Their advantages
With the two systems they are very powerful engines and more discrete no matter
what their discretion comes as much from the care carried to sound-proofing as
with the technique itself. From where differences between PSA on one 206 for
example and Mercedes and BMW on the trucks of luxury.
They pollute less especially in the transitional stages of acceleration (as long
as calculator will make its job well).
The customers are "captive" one cannot make repair anywhere.
Disadvantage , they are obviously more fragile and
their maintenance is more expensive.
