Injector nozzle for diesel engines is very important for the engine performance, especially the holes on the tip and the seating. But it is not easy to inspect them due to its small sizes. 

Here we tried to use our current digital microscopes and borescopes to see what we can see. 

​

Microscope used: ViTiny UM10. 
Injector Nozzle model: DLLA 146P1581

2. Inspection of the holes by pen-type microscopes. 

The injector nozzle has very small opening at the top. The inner diameter is less than 4mm. Most of microscopes can not see into the deep side of the hole, because there is no light can be shed inside. 

We have one small diameter pen-type USB microscope, model PM-40. PM-40 has a diameter of 3.9mm camera, and is equipped with 4 LED lights at the front of the probe. PM-40 can be focused manually to see close and far. We found that only PM-40 can see into the hole of this injector nozzle.

3. Looking inside the injector nozzle with small diameter video borescopes or fiberscopes. 

The opening of the injector nozzle is less than 4mm. One nozzle sample has inner diameter about 3.5mm and another one about 3.9mm. And the opening goes narrower as it goes deep into the tip side. 

To see inside the nozzle, we has to use a borescope with diameter less than 3.9mm, or even smaller than 3mm. 

We removed locking unlocking mechanism of Ablescopes in 2019 due to large percentage of customers damaged the bending part, the reason is that they have no idea there is the unlocking locking mechanism. This unlocking/locking feature is not obvious to many people, and they do not know what to do when the probe is curved and locked in position. 

At the same time, the built-in locking unlocking mechanism is a very useful feature for many end users. So is there a better way to control bending angles without the built-in locking/unlocking mechanism? We come up a simple add on device. You can make it yourself with a few dollars and a visit to a home improvement store (such as Home Depot or Lowes).  

Another simple locking tool is a caulk gun, like the one shown below:

The caulk gun is a little bit bulky. However it works well with Vividia Ablescope VA-400 and other models. 

We had great time at Oshkosh this year for one week long EAA AirVenture. 

We are glad to exhibit at 2018 Arizona ASA Training & Expo at ​WeKoPa Conference Center & Casino

Two associates from Oasis Scientific attended 2018 Alaska Aviation Gathering held at Anchorage on 5/5 an 5/6.  

We have a great traffic at our booth and many Alaska visitors are impressed with our 180 degree articulating borescopes. 

After the show, we visited Anchorage. We feel that there are not many people in Anchorage during early May. Beautiful snow mountains surround the city, and lakes are gorgeous. We are happy to see some mooses in the City. 

Overall, the trip is wonderful and the show is good place to meet our customers and partners. 

Orlando area is starting to warm up in April. We are glad to exhibit at Sun'N Fun for 2nd time from 4/10 to 4/15. 

Mainly we are showing our innovative articulating borescopes, used for general aviation mechanics and airplane owners who are doing maintenance works. There are so many visitors and sometime we need to run to take a bio-break. 

The show is a success for us. We may need to send more associates next year. 

MRO Americas are mostly for commercial airline maintenance markets. Many exhibitors and visitors are professionals in commercial or military jet airplane maintenance, repair, overhaul industries.  

We are demonstrating our articulating borescopes, including newest 2.4mm two-way articulating videoscope, and affordable USB one-way articulating borescopes.  

This Vividia VA-2-2410 (2-way articulation, 2.4mm diameter, 1 meter long with 4.3" LCD screen) has very nice image quality, bright LED lights. Some customers are highly interested in this slim articulating videoscope. 

We will see you at MRO Americas 2019 in Atlanta. Hope we will bring more innovative products with better services to MRO markets. 

Apple held a big event to promote their products for education on March 27, 2018 with teachers, students and educators from Lane Tech College Prep High School, Chicago.
​
We are pleased that our wifi wireless microscope were featured with other products on this event. (The slide is shown at around 33:30" if you watch the video on Apple's website.)

We had great time at Vision Hi-Tech Training and Expo 2018 to connect with customers and fellow exhibitors. Our articulating borescopes received great response and feedbacks from automotive mechanics.  

Our Vividia Ablescope 180 degree articulating borescopes are quite popular among aviation mechanics/technicians, airplane owners and pilots who do most of their airplane maintenance. One place we can meet many aviation maintenance mechanics/technicians is the annual aviation training classes or seminars.  

There are many aviation maintenance / IA renewal training classes in US organized by difference groups. Here is the database on FAA website, where you can do search to find out more information about each training seminars. Some seminars require to register online from FAA website.

The IA renewal training courses are provided many experts from FAA, aviation service providers, aviation magazines, aviation associations, aviation product manufacturers, and training institutions. Here are some courses listed by FAA.  

Concorde Batteries organizes several IA renewal seminars and they compiled a good list of aviation maintenance training classes on their website.

We have great borescopes for general aviation airplane engines (piston engines), and we also have some smaller diameter, long articulating borescopes for jet airplane engines. We welcome you to give us suggestions on how to improve our products. You can call us at 864-469-0919 or send us email at info@oasisscientific.com
