The only way is Essex – the only car is Ford! But Petrol or diesel?

Posted by:

Essex is the county for Ford; it always has been.  But which way is Ford going right now?

Is Ford dedicated to diesel or is it petrol power that it wants to champion?

You could be forgiven for  thinking that Ford  has a foot in  both the Petrol and Diesel  camps.

Dagenham and Dunton

Down in  Dagenham Essex,  Ford build  1 million diesel engines per year! Meanwhile  just up the road at Dunton in Essex

Eco-Boost Engine

Ford engineers and technical wizards are responsible for Ford’s  new engine,  the 1 litre eco-boost.

The Eco-boost engine

This is a petrol engine with the  emphasis on small – it’s just 999cc – low emissions,  high economy.
All three of these credentials are needed if Ford is to show itself as a ‘green’ car company.

Is it petrol or diesel?  The pendulum swings backwards and forwards between these two fuels.
Recently the number diesel cars over took the petrol ones in terms of number sold but is that a good thing?

Diesel and Petrol

Diesel produces less CO2 than petrol, but twice the level of harmful oxides of nitrogen (NOx) and 22 times more particulates!

Particulates are minute specs of carbon which when released into the air can be inhaled deep into the respirtory system.
Some scientists claim they cause a considerable number of premature deaths in the UK and elsewhere.
Some claim that this is a poisonous, invisible smog  and not enough is being done to combat it
Enter Ford with the 1 liter eco-boost engine. It’s a 3 cylinder engine with 999cc and producing 123 brake horse power. Added to these are fuel economy and low emissions.

30 years ago Ford’s 2 litre overhead cam engine produced about 80 bhp;
times have changed but how have these improvements been achieved?

How is the economy achieved?

diesel and petrol engines

Twin variable cams

How is it that an engine half the size of the 1980’s 2 litre  can produce around 54% more power? There are 3 important features of the eco boost engine which make it perform so well.
First of all it is turbo charged. . working off the exhaust gases the turbo rams more air into the engine. Increasing the oxygen in this way makes the engine work more efficiently

Turbocharger 21st century style

And the turbo charger is electronically controlled. This means that it is more accurate. It delivers the correct amount of air at the correct time in the engine’s cycle.

Secondly it is fuel injected but the injection is direct-injection.

Direct fuel injection

Fuel is sprayed directly into the cylinder and under high pressure.
This means minute droplets of fuel entering the combustion chamber directly and not through a manifold. The result:  the fuel is metered more  efficiently and combustion is  more
complete.

Variable cam timing

The third important feature is variable-cam timing.
The camshaft is part of the engine’s programming.
It tells the valves when to open and shut.
In the 1980’s engine the cam was in a fixed position regardless of engine speed.
The eco boost is a twin variable-camshaft configuration; this allows finer control under varying engine conditions and is another powerful way of increasing efficiency.

Ford has a lot to gain by appearing as a green car company.
It wants to sell a lot of cars and in order to achive this it must move towards ever greater efficiency in the engine department.
