As you know, as there has been a great stir, the speed limits in the city have changed. In a large part of the city, cars must go at a maximum of 30 km / h, a new rule that aims to reduce accidents and lower pollution. But, despite good intentions, this last point is quite debatable, as there are certain problems associated with low speed. Let’s talk about the major breakdowns that the new speed limits will cause.
If most of the cars that circulate in our country were hybrids or electric, this new regulations it would have few drawbacks. In these cases, driving at low speed means going most of the time using the electric motor, in the case of hybrids, being ideal to reduce consumption and pollution. But the truth is that the fleet is mostly made up of vehicles with internal combustion engines with years on, cars not developed to run constantly at low speed.
In most cases, circulate at 30 km / h It forces us to drive in first gear, this being dangerous for the mechanics and little benefit for consumption. The aforementioned fleet has an average of 13.2 years, an average that is on the rise. And taking this average into account, there is little discussion about the risk of breakdowns.
If a driver is forced to drive at a low speed, such as 20 or 30 km / h, he will not be able to circulate most of the time in second gear, because in this gear the revolutions will be abnormally low and on any slope he will have to return to use the first gear to get power from your car’s engine. If this custom is prolonged in time the consequences are catastrophic for different parts of the mechanics.
When driving is based on gas and retention, the engine studs must absorb more movement than they should, forcing us to change the silentblocks on a regular basis. With this high load to which the engine is subjected, the bearings are also compromised, as is everything that has to do with cooling in older cars. The vibrations and efforts are negative, not to mention that the anti-pollution systems, the EGR and the filter, will not have a constant regime of work to perform their function correctly.
For cars diesel it will be a real hell, although it is also negative for any internal combustion car. The clutch may also be affected, an element that if it breaks down will ruin the month, or the year.
