Believe me I fully understand how combustion operates in internal combustion engines. Diesel is full air, no throttle (though some rare versions do/did have a throttle), so they do not run at the ideal 14:1 stoichiometric ratio. The rattly noise is that they are too lean (too much air) at low revs/loads. When they are at 70mph on Mways they quieten down as the stoichiometric is neared or met.
When cold, diesel engines can be difficult to start because the cold mass of the metal of the cylinder block and cylinder head absorb the heat of compressed air in the cylinder, preventing ignition. Preheat the engine then this is not a problem as the metal is warm. To overcome this starting problem they use glowplugs to aid in keeping the compressed air hot in the cylinder (not lose its heat to the surrounding cold metal). If the air compressed by the piston is too cold, the fuel sprayed in to the combustion chamber by the injector will not ignite.
This is old hat technology that will be phased out soon enough for electric or hydrogen. Cruise liner operator are looking to hydrogen fuel cells to operate in the sensitive sunshine ports like Venice.

In Westminster we have over 450 on-street electric vehicle (EV) charge points, ranging from 3kw to 22kw, with more being added to provide greater coverage for the growing number of EV owners in the City.
That is just Westminster alone. You can request to have a charger outside your home.

There are many benefits to owning an electric vehicle including free on-street parking in Westminster (when charging) and no congestion charge.
