Guide to vehicle fuel efficiency
This article will bring you the first part of the tricks that will help you with cutting your spends and increasing the efficiency of your car.
Things you can change on instruments are:
Fuel economy OBD-II computer - Fuel consumption feedback will help you gauge how your driving techniques affect fuel usage and it will be crucial in assessing the efficiency of the various modes you try out. That will require low mechanical skills, but it will cost you.
Fuel consumption computer - A DIY, open source digital fuel economy display for cars with electronic fuel injection is ideal for people with older cars where a commercial OBD-II computer can’t be used or it is too costly, and it will require little bit more of mechanical skills.
Vacuum gauge- for this you will be needed not o much money, but some serious mechanical skills and you should use it to monitor your engine’s load for better fuel economy.
Lean burn indicator- if you have this indicator, keep it in lean burn mode and it will save your fuel. This will require medium cost, and also medium mechanical skills.
With aerodynamics, there are two types of alterations that can help with fuel saving. First is removing unnecessary details from your car. It will help if you remove your roof rack when you are not using it. Raised wing type rear spoilers- this doesn't bring anything meaningful to speed.
Radio antenna - you should either remove your antenna or to move it on some more aerodynamic place.
Wind shield wipers – front wipers affect airflow of vehicles. Take off you blades and keep them in your car until you need them.
Mud flaps – it is more important to have clean airflow than clean car.
Side mirrors – High efficiency concept vehicles don’t have side mirrors because they increase both frontal area and Cd. You can replace outside mirrors with smaller mirrors, or more aerodynamically shaped mirrors from similar models. Otherwise, replace the outside mirror with convex, in-car mirrors or extra width rear view mirrors. Cameras and LCD screens a pricier option.
Shave badges, door handles, rain gutters, etc- shaving your door handles and smoothing out all the lines on your car won’t make a huge difference but it will help.
All these alterations will not cost a lot of money, not take lot of time and you do not have to be too skilled.
Second thing that you can do on aerodynamic are fabrications.
Smooth wheel covers-often called moon caps or moon eyes, smooth wheel covers cut down on aerodynamic drag and can be aesthetically pleasing.
Usage of a more aerodynamic front bumper- if your car allows you to swap between bumper styles, try one that is more aerodynamic of modify your existing bumper.
Grill block-use a grill block to limit the amount of air that enters the engine bay which will reduce the aerodynamic drag.
Boat-tailing tires- individual tires can benefit from boat-tailing.
Rear wheel skirts- covering the rear wheels will smooth airflow at the rear of the vehicle.
Sealed panel gaps- you can use clear tape, color matching silicone filler or foam weather stripping to seal panel gaps.
Full boat tail- the full boat tail dramatically reduces rear pressure drag and minimizes trailing wake. This mod will have will large effect on fuel consumption.
Decrease hood to windshield angle-This one requires significant fabrication. Decreasing the angle between the hood and windshield reduces the amount of pressure build-up at its base and can help maintain laminar flow at the windshield/roof transition.
Upgrade headlights-older headlights assemblies sometimes have a bucket-style scoop design. Normally these can be swapped out for different style headlights or modified to cut down on aero drag.
Tyre spats or fully contoured deflectors- these direct flow around tyres in a way that means drag is reduced.
Belly pan/under tray- most vehicles will benefit by fitting a smooth undertray to the underside of the car.
Front wheel skirts – these are much harder to make than rear skirts because the front wheels must turn.
Front wheel arch gap fillers-almost a partial wheel/fender skirt, this could be used in combination with a smooth wheel cover to provide some of the positives of a full skirt.
Frontal area reduction-this includes any major modification that reduces frontal area.
Frontal air dam-extending a dam to the level of the lowest under body component diverts air away from and around the most aerodynamically “dirty” area of most vehicles.
All these alterations are there to improve the aerodynamics of your car, and all of them will require a little bit more money and lot of skills, but it will be worth.
