Our plane [is a] C172 with G1000 and TIS. [An] experimental called position [inbound to the same airport]. We responded with our position. He said we will probably beat him in as he had 80 for ground speed; 29 KT wind. We began our descent to 1;100. TIS reported a target moving from east to west in front of the [experimental]. We let [him] know of the target. He said he was looking 'no joy.' TIS showed a conflict with our path. C172 pilot and passenger [were] visually looking for target; but it was pretty hazy. TIS shows no plane is moving behind or ahead on intersecting path. We decide to Vy climb at full power. [We were] still looking and still no visual contact. I was taught that the best thing to do is climb in potential conflict as the plane becomes much more visible by showing more surface area.TIS showed a -40 and target passing directly underneath. TIS changed Target to yellow and audible 'traffic' alarms trigger. At this point I noticed [I was] in Vy climb at 2;500 FT [and in Class B]. [I] began immediate descent back under the 2;000 FT [Class B] shelf and set up for entering the traffic pattern. The [applicable] FAR here is 'A pilot may deviate from the FARs as much as necessary to maintain the safety of his plane and crew.' [I] made call [at] 2 miles for mid 45 upwind for 15. Turn on the ADSB to report all the time not just when a sender lights it up.
C172 pilot reported an NMAC with an experimental aircraft at a non-towered airport and during evasive action he entered Class B airspace.
