Buffy, I think you will find that the 1,3L is a different animal to the 1,2L as there is such a range of improvements made to this Renault / Nissan / MB Motor. Here are a couple of comments on what you mentioned if of interest - Dave
Cylinder head : The new engine's compact form allows for more room under the bonnet, as well as reducing overall vehicle weight. It features a new triangular-shaped ‘delta' cylinder head. The injectors are centrally installed for better combustion
The exhaust manifold is partially integrated into the cylinder head for more efficient cooling of exhaust gas and more efficient combustion, particularly at low engine speeds and high loads
A Gasoline Particulate Filter has been added. The filter destroys particles in the exhaust gases by trapping them in a microporous honeycomb structure that regenerates automatically at regular intervals
Bore spray coating : For the first time the Alliance is applying this technological innovation to a volume model's engine
Using a plasma torch, a fine film of very hard steel is sprayed on the shafts of the cylinders to enhance heat conductivity during combustion
Aside from creating significant savings in mass, this technique greatly decreases uncontrolled detonations (clicking) in the engine and increases the compression rate for greater efficiency
Bore spray coating is responsible for a 1% reduction in consumption and emissions
