RTA Smart Drive app is better than Google Maps and Sygic in UAE Based on thorough test by many users we officially confirms that RTA Smart Drive navigation app is much better, intuitive and user friendly than Google maps and Sygic (offline maps) in the UAE. Launched by Dubai Roads and Transport Authority (RTA) in late 2014, RTA Smart Drive app gained tremendous initial response and then consistent growth in number of users due to it's local intelligence. RTA Smart Drive app tries to help motorists drive faster by selecting the shortest route that have less congestion based on real-time traffic information. Although this app works in whole UAE, but it works the best in Dubai due to it's aggressive real-time feed from below various sources: Traffic congestion reported by the flow of 8,000 taxis People reporting traffic obstructions through app Surveillance cameras on intersections Accidents reported by Dubai Police Planned traffic diversions by RTA RTA Smart Drive app notable features that making it better than Google Maps: Intuitive Speed Limit Display: Very intelligent and intuitively placed on top left corner and will only display when you exceed limit and then disappear when you are with in speed limit. It also flashes the red circle when you exceed speed limit beyond the 20 kms grace limit on most of the Dubai roads. Closest Fuel Station Display: Very thoughtful of RTA to add one or two nearest fuel station displayed all the time on top right corner so that drivers can plan their fill-up and breaks on the route. Accurate Live Traffic System: Highly accurate and most updated live traffic has been used within Dubai for the success of this great free app for the motorists. RTA combines the feed from Dubai police, Dubai Taxi's, Surveillance Cameras etc to keep this live feed reporting the most latest congestion and accidents on the Dubai roads. Although this app works in whole UAE, but without live traffic layer for outside Dubai area. By planning the fastest and shortest route with no congestion you can save fuel cost by hypermile. Extensive Local Support: Dubai RTA is providing amazing local support via email and plenty of YouTube videos to educate motorists to use this app more efficiently and benefit everyone by reducing the traffic congestion on the Dubai roads. Display Latest Detour and Under Construction Areas: With plenty of development here in Dubai, road maps are always evolving and updating on daily basis. This RTA Smart Drive app shows all the planned traffic diversions, detour and even factor them while planning routes and offer the various choices based on drive time and distance. This way you can also avoid plenty of RTA Fines and Traffic Fines in the UAE. Routes with multiple destinations: This rarely used but great feature that has been missed out from almost all navigation apps, makes it way in RTA Smart Drive. Now you can plan your route from Bur Dubai to JLT and add stop-over at Karama and Al Quoz to pick your friends on the way. Offline Maps: Using mobile data is not always desirable by many users, hence RTA Smart Drive answers this need very nicely that once installed and updated over wifi connection, it works absolutely great without internet connection except the live traffic layer that needs tiny bit of mobile data to fetch the latest congested routes. Breadcrumb trail: Small feature but very useful to see the purple breadcrumb trail of the road behind you while driving. This will definitely help the user when in new area, so that they don't circle same area more than once. Stopwatch timer: Last but not least, RTA Smart Drive features the stopwatch timer to record the distance, time, top speed and average speed from point A to B. Now you can record your best lap to office daily.

Hi Hudad, I find it strange that your mechanic is assuming that the misfire is caused by low compression on one cylinder. The fact is that there are so few diesel engines in the UAE that many mechanics can go for several years without ever seeing even the most basic problems on diesel engines. This is off course not their fault, but let us look at the problem in a logical way; Diesels use compression to heat up the air/fuel mixture to the point where it ignites spontaneously. This means that the compression in each cylinder is of critical importance, but a defective injector that injects too much, or too little fuel can also cause a misfire because like a petrol engine, a diesel requires an exact amount of fuel before the air/fuel mixture will ignite. In practice, too much diesel floods the cylinder, and too little diesel starves the cylinder. Much the same thing happens on petrol engines where fuel pressure or injector problems can either starve or flood the engine. The amount of diesel injected into a diesel engine also plays a big part in the final compression, but since diesel engines are much more sensitive to compression than petrol engines are, a misfire, and especially a misfire at idle can have many causes apart from low compression due to leaking valves, rings or a cylinder head gasket. There is no way of telling without a compression test, assuming of course that the misfire is not caused by fuel delivery issues. However, a simple compression test on either a diesel or petrol engine is not always the best way to identify a problem. A much better way to identify small compression losses on both diesel and petrol engines is to do a cylinder leak down test, where the cylinder is placed under pressure while all the valves are closed. Off course, no cylinder is 100% leak proof, but the rate at which the pressure drops is an indicator of how big the overall compression loss is. Pressure can escape through leaking valves, past rings, or through leaks in the head gasket. In the case of a head gasket, the coolant will bubble, or spill out of the radiator, while if it escapes through valves, you can use a stethoscope to identify which valve is leaking by listening for a hissing sound from either the exhaust or the inlet manifold. If the leak is past the rings, there will be hissing sound from the oil filler cap or the dipstick, or both, depending on how fast the pressure is escaping. On blown cylinder head gaskets, the pressure drop is usually quite dramatic, especially if the leak path is between two adjacent cylinders, on one of which there will always be valves that are not fully closed. This test works on both petrol and diesel engines, but you need some experience in doing this test to be able to interpret the results correctly. With compression tests where gauges are screwed into spark plug, or injector holes in the case of diesels, the result can be wildly inaccurate for a number of reasons, chief among which is the fact that small leaks are often not detected because the piston is compressing the air in the cylinder too fast, not allowing small amounts of air to escape fast enough to be detected. This is true for both petrol and diesel engines, so even if the compression gauge says that the compression is fine on all cylinders, there might still be minor compression losses that the gauge does not detect, which could cause misfires on diesels at idling speed. However, on petrol engines, the engine management system often detects misfires that many of us don’t even know are present because they often present no symptoms other than a CHECK ENGINE light and a stored trouble code. A cylinder leak down test will often identify the problem sooner than some inexperienced mechanic can by changing lots of parts in the hope of hitting on the solution by accident.
